What deadly Venus can tell us about life on other worlds

Even though Venus and Earth are so-called sister planets, they're as different as heaven and hell. Earth is a natural paradise where life has persevered under its azure skies despite multiple mass extinctions. On the other ...

Second night of auroras seen 'extreme' solar storm

Auroras lit up skies across swaths of the planet for the second night in a row on Saturday, after already dazzling Earthlings from the United States to Tasmania to the Bahamas the day before.

Astronomers are on the hunt for Dyson spheres

There's something poetic about humanity's attempt to detect other civilizations somewhere in the Milky Way's expanse. There's also something futile about it. But we're not going to stop. There's little doubt about that.

NASA's Chandra notices the galactic center is venting

Using NASA's Chandra X-ray Observatory, astronomers have located an exhaust vent attached to a "chimney" of hot gas blowing away from the center of the Milky Way galaxy. Their paper describing these results is published in ...

Hubble Space Telescope glimpses spiral galaxy UGC 9684

The celestial object showcased in this image from the NASA/ESA Hubble Space Telescope is the spiral galaxy UGC 9684, which lies around 240 million light-years from Earth in the constellation Boötes. This image shows an impressive ...

First 'extreme' solar storm in 20 years brings spectacular auroras

Earth was set to be struck by more powerful solar storms on Saturday, a day after the most extreme events in two decades triggered spectacular celestial light shows from Tasmania to Britain and threatened possible disruptions ...

Image: Bolivian salt lakes from orbit

This Copernicus Sentinel-2 image features salt flats and lakes in southwest Bolivia, near the crest of the Andes Mountains.

NASA images help explain eating habits of massive black hole

In images from NASA's retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams can help explain ...

Looking for life on Enceladus: What questions should we ask?

Does life exist beyond Earth? One of the most compelling places to consider this possibility is Enceladus, a moon of Saturn with a liquid water ocean encased in a frozen shell. There, plumes of water spray from ice fractures ...

What can early Earth teach us about the search for life?

Earth is the only life-supporting planet we know of, so it's tempting to use it as a standard in the search for life elsewhere. But the modern Earth can't serve as a basis for evaluating exoplanets and their potential to ...
