The NASA/ESA Hubble Space Telescope is back in business. Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147, lies in the constellation of Cetus, [...]

Have you ever heard the sound of stars? Scientists have recorded the sound of three stars similar to our Sun using France’s Corot space telescope. A team writing in Science journal says the sounds have enabled them to get information about processes deep within stars for the first time. If you listen closely to the sounds [...]

Scientists at NASA’s Phoenix Mars Lander project must prepare for the worst since the probe have entering safe mode on October 28 as a response to a low-power fault brought on by deteriorating weather conditions. While engineers anticipated that a fault could occur due to the diminishing power supply, the lander also unexpectedly switched to [...]

We usually have an image of scientists who study the Universe doing so peering through a telescope. And, effectively, this is what astrophysicists do: gather data about the observable phenomena of the Universe. However, in order to interpret this data, i.e. to explain the majority of the phenomena occurring in the Universe, complicated calculations with [...]

This picture of a crater resembling a “happy face” was acquired on 28 January 2008 by The Mars Reconnaissance Orbiter (MRO) Context Camera (CTX). The unnamed crater is about 3 kilometers (1.9 miles) across. It is located among the Nereidum Montes, north of the Argyre basin, near 45.1°S, 55.0°W. North is toward the right and [...]

The “birth rate” for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope. So it is fortunate that the emerging stars give themselves away by a characteristic signal known as [...]
