One day we might seed the universe with life. But should we?

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will explode and irradiate all life, a black hole will engulf the Earth, a Mars-sized interstellar asteroid ...

Four new gamma-ray millisecond pulsars discovered

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang radio telescope at the Parkes Observatory in Australia. The discovery was detailed in a research paper ...

Partial solar eclipse in northern areas on Saturday

The moon will cross in front of the sun for around four hours on Saturday, creating a partial solar eclipse that careful skygazers will be able to see in parts of the Northern Hemisphere.

Image: Hubble captures the Small Magellanic Cloud

Say hello to one of the Milky Way's neighbors! This NASA/ESA Hubble Space Telescope image features a scene from one of the closest galaxies to the Milky Way, the Small Magellanic Cloud (SMC). The SMC is a dwarf galaxy located ...
