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).
A strange lithium signal suggests the star TOI-5882 may have consumed a planet in its recent past.

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.

Numerical relativity may let scientists test early-universe ideas once considered beyond the reach of physics.
SpaceScientists use Einstein’s equations to reveal what came before the Big BangJoseph Shavit
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.
SpaceShadow Blaster points to starburst galaxies as hidden sources of cosmic neutrinosJoshua 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.

A1689-zD1, a galaxy seen 700 million years after the Big Bang (background), with the ALMA-detected [O I] line shown as contours and a spectrum. This is one of four galaxies studied in this paper.

Physicists tracked dark points inside light in real time and found many appeared to move faster than light without breaking relativity.
SpaceDarkness can travel faster than the speed of light — without breaking Einstein’s relativityJoshua Shavit
New Moon impact models suggest South Pole-Aitken ejecta may place deep mantle material near Artemis south pole landing zones.
SpaceNew discovery reveals how the Moon’s largest and oldest crater formedJoseph Shavit
This portion of the universe generated from dark matter halos in the Uchuu simulation shows the distribution of galaxies and quasars up to billions of light-years away.

The night sky looks crowded, but physics may keep distant civilizations from ever meeting or even noticing one another.
SpaceThe harsh physics behind interstellar travel and why Earth may never be visited by aliensJoseph Shavit
New calculations show how a collapsing star might form a gravastar, avoiding a black hole’s singularity and event horizon.
SpaceCollapsing stars could form gravastars instead of black holesJoshua Shavit
A new study suggests alien life could be going undetected because scientists focus more on avoiding false discoveries than missing real ones.
SpaceScientists warn we may be missing signs of alien life across the universeJoseph Shavit
Artist's impression of the exoplanet WASP-121 b. It belongs to the class of hot Jupiters. Due to its proximity to the central star, the planet's rotation is tidally locked to its orbit around it.
SpaceJWST finds rare planet with different atmospheric conditions at dawn and duskJoseph Shavit
Sahara angrite meteorite offers direct evidence that a lost early protoplanet was far larger than once believed.

An artist’s impression of the galaxy CRISTAL-02, with a huge plume of cold gas extending away from it. This plume is almost as long as the galaxy itself, which is a telltale sign that gas is being driven out of the galaxy.
SpaceGalaxy-killing wind may explain why giant galaxies died so earlyJoseph Shavit
Astronomers found the earliest flickering quasar yet, revealing a thin, mature-looking disk around a young supermassive black hole.
