Ancient 'guest star' may mark rare collision of stellar corpses

Centuries after Chinese and Japanese astronomers spotted a bright light in their skies, astronomers have pinned it to a stellar collision that unleashed a rare supernova 850 years ago. A researcher has photographed the structure of Pa 30, ...

SpaceX Falcon Heavy launch spotted from space station (photo)

The launch of SpaceX's most powerful rocket over the weekend was visible from orbit. A SpaceX Falcon Heavy lifted off Sunday (Jan. 15) from NASA's Kennedy Space Center in Florida, sending multiple satellites aloft for the U.S. Space Force on a mission ...

Brilliant green comet loses part of its tail to solar storm in this stunning astrophotographer photo

An image taken by an Austrian comet hunter reveals a disconnection in a stunning green comet's tail that may have been caused by turbulent space weather. Seasoned astrophotographer Michael Jäger took this image of the Comet C/2022 E3 (ZTF) on Tuesday ...

Black holes at galactic centers blast out 10 times more light than previously thought

Black holes residing at the center of galaxies produce way more energy than scientists previously thought, a new study has revealed. These so-called active galactic nuclei devour huge amounts of matter, releasing massive amounts of energy in the form ...

What time is the conjunction of Venus and Saturn on Sunday (Jan. 22)?

This weekend offers a fantastic opportunity to see two of the solar system's planets line up in the night sky. Venus and Saturn will be in conjunction, meaning they'll share the same right ascension — the equivalent of longitude in the celestial sphere ...

Light pollution is erasing stars from the night sky at breakneck pace. It's only going to get worse.

Light pollution is brightening up the night sky so fast that stars are virtually disappearing in front of sky-watchers' eyes, a new study has revealed. Where 18 years ago, a star ...

What Is NASA's Habitable Worlds Observatory? Inside the Plan to One-Up Webb

Just over a year ago, when NASA's James Webb Space Telescope switched on, dominating headlines of even mainstream media, it felt like the start of a new era. Booted up with infrared sensors and crowned with 18 gold-plated mirrors, the JWST reminded the ...

See '3 days in the life' of gorgeous green comet as it heads towards Earth (photo)

The comet's long orbital period (the amount of time it takes to complete one orbit of the sun) means that C/2022 E3 (ZTF) hasn't been seen from Earth in some 50,000 years.
