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 […]

After more than a decade of planning, preparation, frustration and cancellation, in just 11 days’ time the first human-capable vehicle for […]

Morpheus Prototype Lander Ready for New Series of Flight Tests at Kennedy Space Center

Morpheus taking flight for Free Flight 14 on May 28, 2014. Although #14 represented the end of the team’s flight test campaign, more data is needed, and so Project Morpheus is readying to take to the skies again, with the first tethered flight test expected to occur this week.

Construction Site Ahead: Hubble Observes Planet-Forming Circumstellar Dust Disks in Great Detail

A set of high-resolution images of the vast circumstellar debris disks around 11 nearby young stars, which were obtained with the Hubble Space Telescope, have helped astronomers to study their complex and dynamic structure for the first time in great detail. This visible-light survey, called HST/GO 12228, was done with Hubble’s Space Telescope Imaging Spectrograph (STIS), […]

The Case of the Exocomets Around Beta Pictoris

An artist’s impression showing exocomets orbiting the star Beta Pictoris. After analyzing archival observations that had been made with the HARPS spectrograph at ESO’s La Silla Observatory in Chile, astronomers have discovered two families of exocomets around this nearby young star.

With the recent close flyby of comet Siding Spring […]

The Continuing Saga of Planet X: Could More Massive Planets Hide Beyond Pluto?

When it comes to planetary rings, what do you think of? Saturn is the first obvious thing that comes to mind, with its famous majestic ring system surrounding the gas giant planet. The other gas and ice […]

Comet or Asteroid? Herschel Space Observatory Detects Water Outgassing on Dwarf Planet Ceres

A team of astronomers using ESA’s Herschel Space Observatory have discovered clear signals of water vapour coming off Ceres. Image Credit: ESA/ATG medialab/Küppers et al.

A new study published online in the weekly scientific journal Nature on Jan. 22 reports on observations made by the Herschel Space Observatory of water vapour seen coming out […]
