There's no map showing all the billions of exoplanets hiding in our galaxy -- they're so distant and faint compared to their...
Artist concept of Haumea, with the correct proportions of the main body and the ring. The ring is at a distance of 2287 kilometers from the center of the main body and is darker than the surface of the...

As NASA's Cassini spacecraft made its fateful dive into the upper atmosphere of Saturn on Sept. 15, the spacecraft was live-streaming...
Sun-like star Kronos shows signs of having ingested 15 Earth masses worth of rocky planets, prompting Princeton astronomers to nickname it for the Titan who ate his young. This artist's rendering of the diverse rocky planets in our galaxy...

In the image above obtained with the NASA's spectrograph IRIS, can be seen in the bedge or limbo of the Sun the multitude of jets leaping the surface. In the center image, the numerical model is able to reproduce...
This image shows V1247 Orionis, a young, hot star surrounded by a dynamic ring of gas and dust, known as a circumstellar disc. The disc can be seen in two parts: a clearly defined central ring of matter and...
The NASA-funded FOXSI instrument captured new evidence of small solar flares, called nanoflares, during its December 2014 flight on a suborbital sounding rocket. Nanoflares could help explain why the Sun's atmosphere, the corona, is so much hotter than the...
