We’ve wondered about Ceres‘ nature and true identity for over two centuries, ever since it was discovered on New Year’s Day, 1801, by Giuseppe Piazzi of Italy. It’s been alternately classified as a planet, asteroid, and more recently as […]

Astronomers Measure Galactic Winds at Milky Way's Center, Detect Record-Breaking X-Ray Flares From Its Supermassive Black Hole

A composite image of the area around the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), taken with NASA’s Chandra X-ray space telescope. The colors in the main image represent medium, and high-energy X-rays as red, green, and blue respectively. The inset box shows a giant […]

Comets? Asteroids? Or what?

One of the most basic questions driving Astronomy and Space Exploration is: Where did the water […]

Dawn Spacecraft Takes Its Best-Yet Image of Dwarf Planet Ceres

The best image of dwarf planet Ceres obtained so far by the Dawn spacecraft, from 740,000 miles (1.2 million kilometers) away. Images will get much better as the spacecraft approaches Ceres over the next few months. Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

The Dawn spacecraft continues to make its way closer to a world which still hasn’t […]

As NASA gears up for its historic Dec. 4 Exploration Flight Test-1 (EFT-1) flight that will test the Orion space capsule’s systems, the agency announced it had installed the Orion spacecraft’s […]

Cosmic Ray Hit Causes Small Delay at Dawn's Rendezvous With Ceres Early Next Year

An artist’s concept of NASA’s Dawn spacecraft exploring Vesta and Ceres in the asteroid belt between Mars and Jupiter. Dawn had recently experienced an anomaly in its ion propulsion system resulting from a cosmic ray hit, which will cause a small delay to the spacecraft’s rendezvous with Ceres next year.
