This illustration depicts the Sun-like star TOI-791 and two giant planets that NASA's TESS space telescope discovered in its orbit. These planets, designated TOI-791 b and TOI-791 c, are roughly the size of Jupiter

NASA discovers the ‘puffiest’ two planets in our universe

TOI-791 hosts two giant super-puff planets whose ultra-low densities challenge current ideas about planet formation.

A new analysis suggests a ring wormhole could, in theory, form closed timelike curves under the right gravitational conditions.

Space Wormholes may enable time travel, astrophysicists find Joseph Shavit

Asteroid impacts may have shaped early Earth into a network of hydrothermal systems that supported life’s beginnings.

New models suggest Earth may avoid being swallowed by the dying sun, though its fate still depends on uncertain stellar mass loss.

Space Earth may not be swallowed by our dying sun after all, study finds Joseph Shavit

Imperial physicists showed a prototype quantum sensor can cancel noise and recover hidden signals.

An artist’s conception of a star engulfing a planet. The blue lines traces the path of the planet as it spirals toward the star and ultimately collides with it (the planet is partially as it crashes into the left-hand side of the star).

Discovered in 2013, the Pink Planet orbits a sun-like star located 57 light-years from Earth. At roughly 25 times the mass of Jupiter, it sits near the fuzzy boundary between giant planets and brown dwarfs.

A conceptual figure of this study. The background diagram represents the history of the Universe stretching from the Big Bang on the left and the modern Universe on the right. ALMA captured the starburst galaxy “Shadow Blaster” in the same direction as the high-energy neutrino event IC 210922A.

Space Shadow Blaster points to starburst galaxies as hidden sources of cosmic neutrinos Joshua Shavit

An image of the excess gamma rays appearing at the center of our Milky Way, overlaid on an optical image of the galaxy. The cause of this excess, and whether it could come from dark matter, has been debated for more than a decade.
