Wildfires burned more than 10 million acres in the United States during the 2020 season. It was the worst season on record.

The Sickle in Leo is an easy-to-spot backward question mark shape made of stars that marks the head and shoulders of the constellation of the lion. The moon sometimes passes in front of the Sickle's brightest star, Regulus.

In November, a new mini-moon began orbiting Earth. NASA later confirmed it's a lost-and-found 60s-era rocket from the Surveyor 2 moon mission, launched more than 50 years ago. Now the object - SO 2020 - is coming close again for one last time. Here's how to see it!

Astronomers have discovered a possible newly-born planet forming within its own "whirlpool" of dust and pebbles, in orbit around a young star 330 light-years from Earth.

In 20-million-=year-old rock off the coast of Taiwan, researchers have discovered what they think is the fossilized burrow of a giant, predatory sand worm.

Earth has had at least 5 major ice ages. Now it appears Mars - the next planet outward from the sun - has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years.

The rate at which ice is disappearing across the planet has been speeding up, by 65% since the 1990s, a survey of global ice loss using European Space Agency satellite data reveals.

This morning - Wednesday, January 27 - 2 NASA astronauts perform the first in a pair of International Space Station spacewalks, to finish installing a European science platform and complete long-term battery upgrade work.

In the animation in this post, the rhythmic movement of newly discovered planets around the star TOI-178 is represented through a musical harmony, created by attributing a note (in the pentatonic scale) to each of the planets. Hear the music of these planets.
