In mythology, the Titan Kronos devoured his children, including Poseidon (better known as the planet Neptune), Hades (Pluto) and three daughters.So when a group of Princeton astronomers discovered twin stars, one of which showed signs of having ingested a dozen or more rocky planets, they named them after Kronos and
Several of the planets orbiting a nearby star may harbor “substantial amounts” of water, astronomers say, including three planets situated in a habitable part of the star’s solar system.The star—called TRAPPIST-1—is an ultracool dwarf star 40 light years away. It is orbited by seven Earth-size planets, according to the
An international team of space scientists has found evidence of what they believe is a remnant of a type Iax supernova—a white dwarf moving in a way that suggests it was blown across part of the universe by the power of a thermonuclear explosion. In their paper published in the
Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, the country's largest Large Hadron Collider research institution. He also writes about science for the public, including his recent "The Large Hadron Collider: The Extraordinary Story of the Higgs Boson and Other Things That Will Blow Your Mind" (Johns
Using smartphones and radio kits, researchers will track changes in how radio waves travel through the ionosphere
As the moon’s shadow races across North America on August 21, hundreds of radio enthusiasts will turn on their receivers — rain or shine. These observers aren’t after the sun. They’re interested in a
It turns out these events could be even more impressive than we thought.
A supernova is the largest explosion you might ever see if you ever get to see it! It’s the death of a star, and stars go out with a bang. They’re still mostly a mystery to science. It’s
A new map of the universe has been unveiled by scientists, revealing the last seven billion years of the history of the cosmos.The results of the Dark Energy Survey show how dark matter is distributed across the galaxy. Until now, scientists used models to show where it fell. These models are
... and vice versa
There's a vacancy at NASA, and it may have one of the greatest job titles ever conceived: planetary protection officer.It pays well, between $124,000 and $187,000 annually. You get to work with really smart people as part of the three- to five-year appointment but don't have to
Spectacular sunsets and sunrises are enough to dazzle most of us, but to astronomers, dusk and dawn are a waste of good observing time. They want a truly dark sky.Not Ned Molter, a UC Berkeley astronomy graduate student. He set out to show that some bright objects can be studied
French scientists have run computer simulations about the formation of Venus that suggest that “Earth’s Twin” once had a thin ocean of water shortly after it formed.The researchers with the Université Paris-Saclay ran the complex simulation and published their findings in the Journal of Geophysical Research. While today Venus is a barren ball
Thanks again, Hubble.
For the first time, scientists have detected water molecules "glowing" around a planet outside our Solar System, giving us the best evidence yet of an exoplanet with a stratosphere.It's a huge find, and one that could tell us a lot more about the science of Hot Jupiters –
The beginning of new solar physics.
The innermost region of the Sun is hidden from our eyes, and it looks like this stealth has enabled the core to conceal a massive secret.For the first time, scientists have been able to accurately measure the rotation of the solar core, revealing that it
