The wobbly surface of dwarf planet Ceres has shifted over the years, resulting an epic makeover of ridges and cracks, scientists say.

Parts of the Jupiter moon Europa's surface may be studded with jagged towers of ice, which could complicate NASA's plans to put a lander down on the potentially life-supporting moon.

NASA's venerable Hubble Space Telescope is in safe mode after the failure of one of its gyros and a problem with another, but the agency said this specific problem did not put the orbiting observatory in jeopardy. SpaceN...

NASA is working to resume science operations of the Hubble Space Telescope after the spacecraft entered safe mode on Friday, October 5, shortly after 6:00 p.m. EDT. Hubble's instruments still are fully operational and ar...

Dwarf planet Ceres experienced an indirect polar reorientation of approximately 36 degrees, a new paper by Planetary Science Institute Senior Scientist Pasquale Tricarico says.

A new investigative technique has shown the latitudinal distribution of ice-rich landforms on Mars. This large-scale study enables future, more detailed investigations to study several young deposits of ice and sediment ...

Jagged ice spikes called ‘penitentes’ on Jupiter’s ocean-bearing moon could pose grave risks for robotic landers --

The Hubble space telescope, which has been in orbit since 1990, is currently out of action because of a gyroscope failure, the US space agency said Monday.

Intelsat says some satellite operators will be forced to buy new spacecraft if U.S. telecom regulators demand the transfer of 200 or more megahertz of C-band spectrum from satellite operators to cellular companies. Space...

Astronomers have carried out a study of almost 300 hundred planetary nebulae in the supergiant elliptical galaxy Messier 87. The new research, published September 27 on the arXiv pre-print repository, reveals essential i...

Astronomers using ESA's XMM-Newton space observatory have captured the X-ray glow (shown here in purple) emitted by the hot gas that pervades the galaxy cluster XLSSC006.

EPFL astrophysicists actively participated in the discovery of a very rare star, which is particularly old and metal-poor. As a messenger from the distant past, it will allow the scientists to learn more about the young ...

Sagittarius A* (Sgr A*), the supermassive black hole at the center of our Milky Way Galaxy, is 100 times closer to us than any other SMBH and therefore a prime candidate for studies of how matter radiates as it accretes ...

Investigating the earliest and least-known phases of the history of the solar system, when the young sun was still enveloped by a disk of gas and dust in which the planets began to form, is probably one of the most compl...
