If a massive star near Earth exploded into a supernova, the result wouldn’t just be beautiful — it would be catastrophic.

Supernova remnants, stellar nurseries and more populate the new edge-on view of the Milky Way as seen from Earth’s southern hemisphere.

A new study reveals an intriguing possibility: asupernova explosion might have sent a surge of cosmic rays toward Earth around 10 million years ago, with consequences etched in ocean rocks. The ...

V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

Astronomers observed the fading light of supernova SN 2025kg, which followed the fast X-ray transient (FXT) named EP 250108a.

Astronomers observe Type II supernova SN 2024bch behaving differently, with energy from Bowen fluorescence rather than ejecta interaction, challenging models of stellar death and high-energy neutrino ...

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can ...

But most of the gold on Earth isn’t in our hands; it’s deep underground. During the planet’s formation, heavy elements like gold and platinum sank toward the molten iron core. Geologists estimate that ...

Portal Space Systems says that a rapid-maneuverability space vehicle called Starburst will leverage technologies it's already ...

Harvard professor Avi Loeb recently reacted to Elon Musk’s remarks about the unusual nickel-to-iron ratio displayed in the interstellar object 3I/ATLAS, made in an episode of The Joe Rogan Experience ...

Bothell-based Portal Space Systems has introduced Starburst, an ESPA-class rapid-maneuverability spacecraft, and confirmed ...
