Space

An expanding mini universe could counterbalance the collapsing matter of a star, thereby creating a stable gravastar.

A Big Bang Inside a Dying Star Could Stop Black Holes from Ever Forming

A Planet So Hot Its Water Falls Apart Has Different Weather at Dawn and Dusk

The team’s new compact and lightweight imaging unit can be installed on a long-term satellite mission. Their simulations show that a comprehensive map of the entire surface might be produced in a few years.

Ten-Kilo Telescope Built Like a Crab’s Eye Could Finally Map the Whole Moon’s Chemistry

Scientists Have Written the Rules for First Contact, and Step One Is Don’t Panic

Artists’ impression of the white dwarf binary ASKAP J1745-5051. The smaller, dense white dwarf star is accreting material from the larger, but less dense red dwarf star. The interaction of their magnetic fields and the heat from the material accretion creates signals in radio and X-ray light frequencies.

A Repeating Radio Pulse Turns Out to Be Two Stars Locked in a Death Spiral

A split image showing an active Sun during solar maximum (on the left, taken in 2014) and a quiet Sun during solar minimum (on the right, taken in 2019).

The Sun Is Squeezing Its Magnetic Activity Toward the Surface and Nobody Knows Why

The left panel shows a hub-filament system observed in an actual star-forming region; the right shows the structure produced by this study's 3D simulation. Both show multiple elongated filaments of gas radiating toward a dense central hub. The study shows that this characteristic pattern can emerge when a fast interstellar shockwave strikes a molecular cloud with a curved magnetic field.

Dead Stars Are Sculpting the Cradles Where New Ones Are Born

A stellar graveyard plot showing all the masses of all the black holes and neutron stars detected by LIGO-Virgo-KAGRA in the latest catalog

The Universe Builds Black Holes in More Than One Way, and We Now Have Proof

The Mathematics That Turns Spacetime Into a Crystal, Then a Black Hole

A view of the Hapcheon impact crater, where researchers identified geological evidence of a post-impact hydrothermal lake environment.

How Asteroid Strikes May Have Sparked Earth’s First Breath of Oxygen

In this visualization, the LEXI instrument is shown onboard Firefly Aerospace’s Blue Ghost Mission 1, which will deliver 10 Commercial Lunar Payload Services (CLPS) payloads to the Moon. Firefly Aerospace

New, Shortest Path to the Moon Turns Out to Run Past the Moon First

Six mix-and-match drink recipes could supply astronauts on long space flights with omega-3 fatty acids.
