For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound microlensing world is a super-Jupiter orbiting far from its host star.

The European Space Agency’s XMM-Newton and NASA’s Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance to these echoes, they found the outer arms to be up to 10% farther away than previously thought.

Modern cosmology rests on a simple assumption: If we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological principle.

A new study by a doctoral researcher at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, suggests global dust storms on Mars may organize the Martian atmosphere into regions favorable for electrical activity, increasing the potential for electrostatic discharges that could affect missions to the red planet by interfering […]

Saturn’s moon Enceladus has become a prime solar system target for astrobiologists. This is because the small moon, which is just over 10% the diameter of Earth’s moon, harbors a vast subsurface ocean beneath its icy crust. This subsurface ocean, combined with the geysers at Enceladus’ south pole that discharge bits of this ocean into […]

When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star’s violent demise. Now, observations from NASA’s James Webb Space Telescope (JWST) may finally explain the planet’s unlikely escape from destruction.
