Our Sun is the very reason life exists on our small, blue planet. It provides solar radiation that warms the planet and ignites the intricate biochemical processes like photosynthesis producing oxygen for life to breathe. However, while the Sun is known for giving life, it can also potentially take it away with its sol
Bezos said we should move heavy industry to the Moon. Musk says we'll have sustainable lunar cities. We know there's ancient water ice in craters on the Moon's poles, but there's not enough water to support a city.
Monitoring Earth from above is a messy, inconsistent business. Clouds can block a satellite view, the angle of the Sun can create huge shadows, and orbital paths might not take a system across the same general area for weeks. That inconsistency is hard to deal with for traditional software, and can even confuse standar
Scientists were shocked when they received the first images of Martian gullies. They were even more shocked as those gullies appeared to change over time. Their similarities to gullies seen on Earth were uncanny, but all of Earth’s gullies are formed by the water run-off, and Martian is too cold and has too sparse an a
We’ve found over 5,500 exoplanets so far. Dozens of them have been in the habitable zone of their parent stars, where, at least in theory, they could host an ocean. But we’ve never definitively found a liquid ocean on another planet. A new paper from researchers Eleanor Cornish and Tyler Robinson of the University of A
The James Webb Space Telescope (JWST) has opened up many wonders of the cosmos to scientists since it began its science operations a few years ago. But one thing that it hasn’t done is find an “exomoon”. These, as yet still theoretical, moons orbit exoplanets in other star systems, and JWST was supposed to find a pleth
What used to be a rare sight gracing the twilight sky is now becoming strangely commonplace. If you live on either U.S. coast, you have to good chance at seeing what’s become a common sky scene in our modern technocene era: a space launch jellyfish.
More good news for NASA's Nancy Grace Roman Space Telescope. The telescope's first mid-course correction was extremely efficient, using only 10% of the fuel allotted for it. This efficiency, coupled with other factors, means the powerful space telescope will likely have an additional ~12 years of observing time.
Researchers have found that if black holes have certain features, known as "hair," then we could prove it by observing the gravitational ringdown of merging black holes. Future studies could test the no-hair theorem of general relativity.
Astronomers used 8 years of observations to create a 3D image of a very young, very massive binary star as it forms. The image shows that the disks in the system are all misaligned. Those misalignments, together with the orbit, are clues to the system's chaotic history.
Most of our experience with the Search for Extraterrestrial Intelligence (SETI) has been focused on capturing radio signals that alien species have sent out, whether intentionally or unintentionally. That creates a huge “synchronicity” problem - what if there aren’t any alien civilizations broadcasting radio signals no
The most comprehensive catalogue of exploding white dwarf stars ever assembled has revealed new clues about dark energy, the mysterious force driving the universe’s accelerating expansion.
