Inside the genius of Albert Einstein

The word genius is often used to describe Albert Einstein, but what exactly earned the German-born theoretical physicist that descriptor? We have his ideas to thank for many facets of the modern world, but it turns out not everyone thought he was that brilliant."Everybody knows who Einstein is and people understand that he was a very famous scientist," says NASA astronomer Michelle Thaller. "But I think that people often don't grasp the true depth and the profound nature of the things that Einst...

Astronomers solve a longstanding artwork puzzle

The origin of Vermeer's acclaimed landscape has long puzzled historians.The painting is of Vermeer's home town, but no one has known when he painted it.A team of astronomers uncover clues hidden in the artwork that reveal its secrets. Just 35 paintings done by Johannes Vermeer survive.The best-known among these, of course, is his captivating Girl with a Pearl Earring. Part of what makes it so arresting is Vermeer's masterful use of light — his model's eyes practically glow with life and intelli...

‘A meteor will go by, and everyone gasps’: meet the world’s most dedicated stargazers

Every year, amateur telescope makers gather under starry skies in the US and South Africa – to trade tips and tales from across the universeYou have to be rigorous. You need perseverance. You must be meticulously clean. But even if you possess all these skills, none of them matters if you are in a hurry. Because there is one thing enthusiasts make clear from the start: building a telescope from scratch takes time. “It will often take a year to make your first mirror,” says Ken Slater, a board me...

NASA to fly a football stadium-sized high-altitude balloon to study light from newborn stars

NASA’s latest mission won’t actually reach space – but it will come very close, with a massive observation craft made up of a football stadium-sized high-altitude balloon, along with a special stratospheric telescope instrument that can observe wavelengths of light blocked by Earth’s atmosphere, cast from newly-formed stars. The mission is called the ‘Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths,’ but shortened to ASTHROS since that’...

A catastrophic asteroid shower hit Earth & moon 800 million years ago

A new study examined data on lunar craters to gain a better understanding of ancient impact events on Earth.Although scientists know of some ancient impacts on Earth, weather and erosion makes it hard to study impacts that occurred beyond 600 million years ago.Studying craters on the moon can provide some clues. Since Earth formed 4.5 billion years ago, it's been bombarded by countless asteroids, meteors and other space objects. We know of some of the major incidents. The Chicxulub impact crate...

SpaceX Satellites Ruin Perfectly Good View of Comet NEOWISE

Nowhere is safe from light pollution, not even space. On Wednesday, astrophotographer Daniel López shared a photo he captured of Comet NEOWISE the day before at Teide National Park on the Canary Islands. However, SpaceX’s Starlink satellites ruined the image, painting streaks across the otherwise largely pristine sky.Read more...

Incredible Image Shows a Pair of Exoplanets Around a Sun-Like Star

This first-of-its-kind image reveals a star system just 300 light-years from Earth. It was captured by the Very Large Telescope (VLT), which is managed by the European Southern Observatory and located in the Atacama desert of Chile. This is considered the first direct image of multiple exoplanets in orbit around a…Read more...

When Astronomer Johannes Kepler Wrote the First Work of Science Fiction, The Dream (1609)

The point at which we date the birth of any genre is apt to shift depending on how we define it. When did science fiction begin? Many cite early masters of the form like Jules Verne and H.G. Wells as its progenitors. Others reach back to Mary Shelley’s 1818 Frankenstein as the genesis of the form. Some few know The Blazing World, a 1666 work of fiction by Margaret Cavendish, Duchess of Newcastle, who called her book a “hermaphroditic text.” According to the judgment of such experts as Is...

In a first, astronomers watch a black hole’s corona disappear, then reappear

It seems the universe has an odd sense of humor. While a crown-encrusted virus has run roughshod over the world, another entirely different corona about 100 million light years from Earth has mysteriously disappeared.For the first time, astronomers at MIT and elsewhere have watched as a supermassive black hole's own corona, the ultrabright, billion-degree ring of high-energy particles that encircles a black hole's event horizon, was abruptly destroyed.The cause of this dramatic transformation is...

Astronomers Have a Plan to Detect a Possible Black Hole in Our Solar System

You may have heard about Planet Nine—a hypothetical planet thought to exist in the outer reaches of the solar system. One possibility is that it’s not a planet at all but a tiny black hole. New research outlines a potential strategy for detecting this supposed black hole, in a search that could begin as early as next…Read more...

A massive star has mysteriously vanished, confusing astronomers

The massive star in the Kinsman Dwarf Galaxy seems to have disappeared between 2011 and 2019.It's likely that it erupted, but could it have collapsed into a black hole without a supernova?Maybe it's still there, but much less luminous and/or covered by dust. A "very massive star" in the Kinman Dwarf galaxy caught the attention of astronomers in the early years of the 2000s: It seemed to be reaching a late-ish chapter in its life story and offered a rare chance to observe the death of a large st...

Beyond Pluto: the hunt for our solar system's new ninth planet

Scientists think a planet larger than Earth lurks in the far reaches of the solar system. Now a new telescope could confirm their belief and change solar system scienceYou’d think that if you found the first evidence that a planet larger than the Earth was lurking unseen in the furthest reaches of our solar system, it would be a big moment. It would make you one of only a small handful of people in all of history to have discovered such a thing.But for astronomer Scott Sheppard of the Carnegie I...

3 scientists school flat Earthers on the evidence

Despite centuries of evidence proving otherwise, there are an alarming number of people around the world who genuinely believe that the earth is flat. Bill Nye The Science Guy, NASA astronomer Michelle Thaller, and Neil deGrasse Tyson strongly disagree.From simple experiments like standing at a seashore or looking through a telescope at other planets, to reading about navigation or viewing photos of Earth taken from space, the scientists share several ways that flat Earthers can see the truth fo...
