Image: NASA's Terra satellite captures 2015 eclipse shadow

During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA's Terra satellite passed over the Arctic Ocean on March ...

Is the universe a fractal?

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it's complicated.

NASA probe makes closest ever pass by the sun

NASA's pioneering Parker Solar Probe made history Tuesday, flying closer to the sun than any other spacecraft, with its heat shield exposed to scorching temperatures topping 1,700 degrees Fahrenheit (930 degrees Celsius).

Image: The twin galaxies NGC 4496A and NGC 4496B

NGC 4496 in the constellation Virgo consists of two spiral galaxies, NGC 4496A (upper large galaxy) and NGC 4496B (lower galaxy). They are in the same line of sight from Earth but located at quite different distances, and ...

Two Earth-sized exoplanets orbiting nearby star detected

An international team of astronomers has reported the discovery of two exoplanets orbiting a nearby star known as HD 101581. The newfound alien worlds are slightly smaller than Earth and orbit its host very closely. The discovery ...

New commercial Artemis moon rovers undergo testing at NASA

Through NASA's Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the moon's south pole region, exploring more of the lunar ...

NASA solar probe to make its closest ever pass of sun

NASA's pioneering Parker Solar Probe is poised to make its closest-ever approach of the sun on Christmas Eve, a record-setting 3.8 million miles (6.2 million kilometers) from the surface.

Hubble spies spiral galaxy NGC 2566

This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and ...
