Moon Crater Named “Carroll” After Astronaut's Deceased Wife

Amid ongoing tensions in the Middle East, a ray of hope for humanity has emerged in the form of Artemis II crew, which is currently the farthest ever manned mission from Earth. If everything works, the next mission, Artemis III aims to land astronauts near the Moon’s south pole, something never done before.

But we are already witnessing history in the making as one emotional moment took the whole world by surprise when Canadian astronaut Jeremy Hansen formally made a request to name a newly discovered crater on the Moon "Carroll", after mission commander Reid Wiseman's late wife. This was followed by a teary eyed group hug.

This was not only a moment of forever love but also a symbol of incredible human strength. The astronauts have also shown how science and faith can co-exist. How some feelings can reach beyond the farthest possibilities, to the far side of the Moon and back to home planet Earth. This is exactly the right time for us as a species to look for peace, not war.

This is also the first time a non-American has traveled to the Moon’s vicinity, astronaut Jeremy Hansen from the Canadian space agency. The astronauts are setting example for future space exploration. They’ll capture ultra-high-resolution images of the Moon and Earth for navigation calibration and geological mapping.

The crew is wearing special radiation sensors because they must spend days outside Earth’s protective magnetosphere, something astronauts haven’t done since Apollo 17 in 1972. The spacecraft will loop around the Moon and naturally fall back toward Earth on April 10 without needing a major burn to return, a safety method also used in Apollo 8.

The mission spacecraft built by European Space Agency will reenter Earth’s atmosphere at about 39,000 km/h, generating temperatures near 2,800°C, testing the new heat shield design. It will test the first human mission with a hybrid international spacecraft, a US-European partnership. This is what humanity should be striving for - consistent collaboration, new discovery and adventure into outer space.

10 Times When Einstein Was Wrong About Physics

Albert Einstein is widely regarded as the greatest physicist of all time. Einstein won the Nobel Prize in 1921 for explaining the photoelectric effect - using Planck's quantum theory. But many argue (rightly) that he deserved a few more Nobel Prizes for works such as relativity, Bose Einstein condensate, etc.

However, there were times when even the genius of Einstein failed to comprehend the complexity of the universe. Einstein's debate with Niels Bohr are still remembered for how wrong Einstein's stance was on the uncertainty principle by Heisenberg. Till the end of his life, Einstein never made peace with the cornerstone of quantum mechanics.

Following are 10 notable times Albert Einstein was “wrong” (or at least incomplete) in physics - not in a mocking sense, but in the very human way. The lesson here is that even Einstein was wrong on many occasions so don't beat yourself up in life!

---

1. Cosmological Constant (his “biggest blunder”)

Einstein added a term (Λ) to his equations to force a static universe, because he believed the universe couldn’t be expanding. Later, Edwin Hubble showed the universe is expanding. Einstein visited Hubble's observatory to confirm the discovery himself. Ironically, his biggest blunder Λ came back decades later as dark energy.

---

2. Rejection of Quantum Indeterminacy

Einstein hated the idea that nature is fundamentally probabilistic. His famous line - God does not play dice with the universe, confirmed Einstein's opposition to the growing interest in quantum mechanics. Bohr famously replied to Einstein - Don't tell God what to do. And experiments later proved that quantum randomness is real, not just due to hidden ignorance.

---

3. Opposition to the Copenhagen Interpretation

Einstein strongly opposed Bohr’s Copenhagen interpretation, which says that tiny particles (like electrons) exist in a fuzzy mix of all possible states (like being in many places at one time) until we measure or observe them. The act of observing forces them to "pick" or "collapse" to just one state. Modern quantum mechanics overwhelmingly supports Bohr, not Einstein.

---

4. Hidden Variables Belief

Einstein was looking for the ultimate theory, the theory of everything being his life goal. He believed that quantum mechanics must be incomplete and that hidden variables would restore determinism. Bell’s Theorem and later experiments (Aspect, Zeilinger, etc.) ruled out local hidden-variable theories.

---

5. Disbelief in Quantum Entanglement

Quantum entanglement is when two or more tiny particles get linked, sharing the same fate no matter how far apart they are. Einstein called entanglement: “Spooky action at a distance”. He believed it showed quantum theory was flawed. Today, entanglement is experimentally verified and used in quantum computing and cryptography.

---

6. Incorrect Prediction About Gravitational Waves (Initially)

Einstein first predicted gravitational waves (1916), then later doubted their existence, publishing a paper arguing they weren’t real. Einstein thought that gravitational waves were merely mathematical artifacts or too weak to detect. He eventually corrected himself and in 2015, LIGO directly detected them.

---

7. Resistance to Black Holes

Einstein was skeptical that real objects, that too stars way more massive than the Sun, could collapse into singularities. He even wrote a paper arguing black holes wouldn’t form in reality. Today, black holes are directly observed, including the first image in 2019.

---

8. Dismissal of Quantum Field Theory’s Direction

Einstein never fully accepted or contributed meaningfully to quantum field theory, which became the backbone of modern particle physics (Standard Model).

---

9. Unified Field Theory Failure

In order to find theory of everything, Einstein spent the last ~30 years of his life trying to unify gravity and electromagnetism. He failed, and his approach turned out to be mathematically elegant but physically unproductive.

---

10. Underestimating the Practical Impact of Nuclear Energy

Einstein initially believed nuclear energy would remain theoretical. Gradually he came to realize with the advent of world wars that nuclear energy could be detrimental for the world. Einstein himself admitted he had underestimated its real-world implications and wrote a letter to Roosevelt not to create atomic weapons.

10 Surprising Facts About Satyendra Nath Bose

1. Despite giving his name to Boson and Bose-Einstein statistics, he never won a Nobel Prize, which is one of the biggest ironies in science history.

2. An impressed Albert Einstein personally translated Bose’s 1924 paper into German and submitted it for publication, leading to the discovery of Bose Einstein condensate.

3. Bose was a brilliant student throughout his academic career. He ranked first in M.Sc. Mathematics at Calcutta University in 1915.

4. Bose had no formal training in advanced quantum mechanics when he derived Bose–Einstein statistics—he arrived at it purely through intuition and symmetry.

5. Bose never received a PhD, yet became a professor and Fellow of the Royal Society (FRS).

6. The term “boson” was coined by Paul Dirac, not Bose himself, to honor Bose’s contribution to physics. Dirac and his wife Margit visited Calcutta in the 1950s.

7. Bose worked closely with Meghnad Saha, and together they translated Einstein’s and Minkowski’s papers into English for Indian students.

8. Bose played a key role in building modern science education in India, especially at Dhaka University and later Calcutta University after division.

9. Bose was nominated for the Nobel Prize multiple times, but the prize committee preferred experimental discoveries over theoretical ones.

10. Bose openly admitted he did not fully grasp how revolutionary his own result was—it was Einstein, not Bose, who immediately realized the importance and applied Bose's theory to matter, thus discovering fifth state of matter.

Nobel Prize In Physics Awarded For Quantum Mechanics

The 2025 Nobel Prize in Physics has been announced to 3 scientists from different nations, whose work has pushed quantum mechanics from a highly conceptual realm to physical devices you can actually hold. The winners are Michel Devoret (France), John Clarke (UK) and John M. Martins (USA).

Their experiments in the 1980s have bridged theory and engineering, paving the way for tomorrow’s quantum technologies, which we actually use today! In simpler terms, they showed decades ago that quantum effects, like tunnelling and discrete energy levels, can manifest in circuits large enough to be held.

What Nobel Committee Said

The Nobel Committee explained why this year's win is crucial for physics and tech world... "they have provided opportunities for developing the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors."

Olle Eriksson, Chair of the Nobel Committee for Physics, said:

It is wonderful to be able to celebrate the way that century-old quantum mechanics continually offers new surprises. Quantum mechanics is the foundation of all digital technology.

Nobel For Macroscopic Quantum Object

Nobel Committee noted that the winners' findings have "brought quantum mechanics from the subatomic world onto a chip."

Reaction of Nobel Laureates

The winners' comments suggest that this was unexpected and a meaningful recognition which they will cherish. John Clarke commented: "It never occurred to me that this might be the basis for Nobel prize." He almost collapsed out of surprise!

John M Martins opened his computer, and saw his picture alongside the other winners, and he was "in shock." Michel Devoret was instrumental in making long-term contributions in superconducting quantum circuits, and thankful for the recognition.

The royal society (UK) of which John Clarke is a fellow, said:

Their experiments revealed that the strange laws of quantum physics apply not only at the atomic scale, but in systems big enough to see and touch.

 

What the winners discovered

The key phenomena involved in the victory are quantum tunnelling and energy quantisation. Quantum tunneling is the phenomenon where a subatomic particle passes through a potential energy barrier that it shouldn't have enough energy to overcome, according to classical physics.

Quantum systems, like electron, can only absorb or emit energy in discrete packets (quanta). In many quantum systems, allowed energy levels are separated by well defined gaps; energy transitions happen when quantum systems, like electron, jump between energy levels.

The breakthrough of the laureates was to show that these effects, long thought to be limited to atoms, molecules or small particles, can appear in macroscopic — i.e. large — systems when engineered correctly.

To study the two phenomena, they carefully controlled parameters like current, voltage, and temperature, and measured the electrical behavior of the circuit which they built using superconducting materials. And all of this was done in the mid 1980s! Their pioneering work led to the technologies in the devices we use today, and will use tomorrow.

How Nobel winners are selected

The Nobel Prizes were established through the will of Alfred Nobel, a scientist, engineer and industrialist, who died in 1896 and left instructions that the bulk of his enormous fortune be used to found annual prizes in Physics, Chemistry, Physiology or Medicine, Literature, and Peace.

Alfred Nobel and Nobel Prize

Nobel Prize in physics is awarded every year, usually announced in early October. For each year’s Nobel Prize, the nomination process begins in the previous year.

Nomination forms are sent out anonymously to select individuals in the field, around 3000 reputed scientists, in September. They nominate candidates for the coveted prize before Jan 31 deadline, but they cannot nominate themselves.

The Nobel committee reduces the nominee list to a shortlist (often ~15 names) and eventually proposes up to three laureates for the prize. In the earlier days, the prize was also given to a single person as well.

Summing up

The 2025 Nobel Prize in Physics is a reminder that quantum mechanics is not just a set of bizarre formulas for electrons, but a living framework that can manifest in engineered devices. Clarke, Devoret, and Martinis converted quantum phenomena into electrical circuits, closing the gap between theory and practicality.

In awarding this prize, the Nobel Committee highlights that years of careful research in basic physics can lead to major technological change. It shows that big breakthroughs often start as simple questions explored with patience in the physics lab.

Organic Molecules Discovered On Saturn's Moon

Discovery of Organic Molecules

Scientists recently confirmed the presence of complex organic molecules in the icy plumes of Enceladus, the sixth largest moon of Saturn. These molecules, some of which are considered precursors to amino acids, the harbingers of life, were detected in ice particles ejected from fissures near the moon’s south pole. This suggests that the moon has the chemical ingredients necessary to support intelligent life.

Why Organic Molecules Support Life

Organic molecules are compounds primarily made of carbon, hydrogen, oxygen, and nitrogen, forming the building blocks of life, such as amino acids, sugars, and lipids. Their presence is crucial because they are the raw materials from which living organisms construct cells, proteins, and DNA. Without organic molecules, life as we know it cannot exist.

How Astronomers Found the Molecules

Astronomers analyzed data collected by the Cassini spacecraft, which flew directly through Enceladus’s geysers. Using onboard instruments, scientists examined the composition of ice grains and vapor, detecting carbon-rich molecules to their surprise. By studying the freshly ejected particles, they ensured that the molecules came from Enceladus’s subsurface ocean rather than being altered by space radiation.

The Cassini spacecraft, launched in 1997 as a joint mission by NASA, ESA, and the Italian Space Agency, spent 13 years exploring Saturn and its moons, studying the planet’s rings, atmosphere, and magnetic field. This discovery by Cassini is a huge success towards finding places in our own solar system which can support extraterrestrial life.

About Enceladus and Its Relation to Saturn

Enceladus is a small, icy moon orbiting Saturn and is famous for its bright, reflective surface. Compared to our Moon, diameter ~3500 km, Enceladus measures small, about only 500 kilometers in diameter and harbors a hidden ocean beneath its icy crust. The moon shoots geysers of water vapor and ice into space, which were studied by scientists through Cassini spacecraft. Enceladus’s relation to Saturn is not just orbital... its geysers feed particles into Saturn’s ring system.

What Scientists Have Said

Scientists have expressed excitement about the findings. One researcher noted, “These organic molecules are some of the freshest we’ve seen in the solar system, and they likely originate from Enceladus’s hidden ocean.” Another added, “Discoveries like this bring us closer to understanding whether life could exist beyond Earth.” 

Existence of Extraterrestrial Life

For life to exist beyond Earth, astronomers believe three main ingredients are necessary: liquid water, organic molecules, and a source of energy. Enceladus has all three, thanks to its subsurface ocean, detected organics, and heat from tidal forces. Scientists emphasize that while this doesn’t prove life exists, it makes Enceladus a prime candidate for habitability studies.

How Gold, Platinum And Uranium Formed?

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth: Richard Feynman.

Water makes up nearly 70% of human body by weight. The components - hydrogen is the most abundant element in the universe and oxygen was forged in the interiors of collapsing stars. While the body is this or that many years old the components are nearly as old as the universe itself!

The first atoms were made approximately 380,000 years after the big bang. Prior to this, the universe was a hot soup of ions and subatomic particles. But as the universe continually expanded, it became less dense and colder allowing the simple atoms of Hydrogen.

Humongous clouds of hydrogen were clumped together under the force of gravity and ancient stars began shaping up. Just like a cotton candy is spun from sugar solution, a star is spun from an uncountable number of Hydrogen atoms. How does a star continually burn? Its source of energy is nuclear - by converting Hydrogen to heavier elements, like Helium - the second most abundant element in the universe.

At the end of a star's life, its main fuel Hydrogen ran out and Helium is converted to further heavier elements like Oxygen and Carbon - building blocks of life. Thus, we can say that we are the children of stars. It is a profound realization that only few can truly appreciate. We are made of star stuff, said astronomer Carl Sagan. The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of dying stars.

In the same capacity, physicist Lawrence M Krauss said - Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. 

Question is, where do rare elements like Gold, Platinum come from?

The answer is rare occurrences - supernova and neutron star mergers. That's what makes these elements so precious! An ordinary star, like our sun, will die a slow death by becoming a white dwarf first and it will gradually cool to a black dwarf.

On the contrary, stars which are 8 times heavier than the Sun will explode in a supernova, flinging debris miles around, destroying themself, leaving behind a crushed reactor core (a neutron star or black hole). Some heavy elements like iron, nickel, and a bit of gold/platinum can be formed during the core-collapse phase of a Type II supernova.

Even heavier elements - Uranium, which is extremely rare, is formed by the merger of neutron stars, a scarce event called kilonova. Also, most of the gold and platinum in the universe are forged during violent neutron star mergers, where extreme gravity and neutron-rich environments trigger rapid nucleosynthesis — in fact, a single merger can produce hundreds of Earth-masses worth of gold.

This was confirmed in 2017 with the gravitational wave event GW170817, when astronomers observed a neutron star merger producing huge amounts of gold and platinum!

And now the data from the James Webb Space Telescope is helping astronomers identify the infrared signatures of freshly formed gold and platinum in distant kilonovae, offering real-time evidence of heavy metal birth in the early universe.

Summing up, everything we are made of, and whatever we have here on Earth, all life, magic and rare wonder, has come straight from the star factories. We are the universe. We are the successor of starry nights, catastrophic explosions and violent mergers.
