By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by ...
Long before a human ever sets foot on the Red Planet, we already know how harsh the environment is. Once a human finally does, the only things protecting them from that environment will be the infrastructure we've built there ...
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
Jupiter's moon Io is the most volcanically active planetary body in the solar system, boasting hundreds of active volcanoes that spew molten lava into space. This activity results from a process called tidal heating, in which ...
Each time the moon covers the sun during a total solar eclipse—darkening daytime skies and briefly revealing the sun's ethereal outer atmosphere, the corona—it presents new opportunities to better understand our star and ...
We've been covering the journey of the Habitable Worlds Observatory for some time now. Over the past few years, it's gone from a proposal to a relatively fleshed-out plan for how and what the next Great Observatory should ...
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
"Dead stars" known as white dwarfs have already shown the potential to help us better understand how planetary systems, including our own solar system, take shape and evolve. Now, research from the University of Michigan ...
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
