Planetary ScienceHow alien ‘canals’ sparked debate over life on Mars
In The Martians, journalist David Baron recounts scientific and public debate over purported intelligent life on the Red Planet.
-
Planetary ScienceCosmic rays could, in theory, sustain life on other worlds
The hypothesis could extend the search for extraterrestrial life to include frigid planets with thin atmospheres and underground water.
-
Planetary ScienceA giant planet may orbit our closest sunlike neighbor
Alpha Centauri A, four light-years from Earth, may host a gas giant. If confirmed, no Earthlike planets orbit in the star’s habitable zone.

Seven superclouds sit just beyond the solar system
The superclouds probably produce star-forming clouds of gas, since most nearby stellar nurseries are located within the giants.
-
AstronomyThe Webb space telescope spies its first black holes snacking on stars
These star-shredding black holes sit within dusty galaxies that block many telescopes’ views. That’s not an issue for JWST.
-
Quantum PhysicsA quantum computer goes to space
Quantum computers in space could be useful for communications networks or for testing fundamental physics.
-
AstronomyTwo colliding galaxies may have birthed this black hole
An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.
-
AstronomyBetelgeuse’s companion star revealed in new images
Revealed by advanced imaging, the long-sought "Betelbuddy" is much smaller and fainter than Betelgeuse and orbits within the supergiant’s atmosphere.
-
Planetary ScienceThis star offers the earliest peek at the birth of a planetary system like ours
A young sunlike star called HOPS 315 seems to host a swirling disk of gas giving rise to minerals that kick-start the planet formation process.
-
SpaceIn a first, an image shows a dying star exploded twice to become a supernova
The image offers the first evidence for a previously unconfirmed origin story of type 1a supernovas.
-
SpaceThe biggest black hole smashup ever detected challenges physics theories
Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.
-
SpaceA newly discovered interstellar object might predate the solar system
3I/ATLAS might be over 7 billion years old, a new study reports, which would make it the oldest comet known. But experts caution we need more data.
