A little more than a year ago a research team started to develop a vital part of a Finnish invention - an electric solar wind sail for interplanetary journeys. Now, a prototype has been successfully manufactured and tested.
University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say "sideline quasars" likely teamed up with it to heat abundant helium gas billions of years ago, preventing small galaxy formation.
About 35 million light-years from Earth, in the constellation of Eridanus (The River), lies the spiral galaxy NGC 1637. Back in 1999 the serene appearance of this galaxy was shattered by the appearance of a very bright supernova. Astronomers studying the aftermath of this explosion with ESO's Very Large Telescope at the Paranal Observatory in Chile have provided us with a stunning view of this relatively nearby galaxy.
The first truly global telescope came a significant step closer to completion this month with the installation and first light on three new 1-meter telescopes at the South Africa Astronomical Observatory (SAAO) near Sutherland, South Africa.
The original Philae comet lander has been travelling through space since 2 March 2004. It is currently in hibernation mode, awaiting its arrival at Comet 67P/Churyumov-Gerasimenko. But the Philae models on the ground are being put through their paces: they are being tested to breaking point and examined by the German Aerospace Center.
A new study using data from NASA's Chandra X-ray Observatory points to the origin of a famous supernova. This supernova, discovered in 1604 by Johannes Kepler, belongs to an important class of objects that are used to measure the rate of expansion of the Universe.
Electrically charged lunar dust near shadowed craters can get lofted above the surface and jump over the shadowed region, bouncing back and forth between sunlit areas on opposite sides, according to new calculations by NASA scientists.
A massive backplane that will hold the primary mirror of NASA's James Webb Space Telescope nearly motionless while it peers into space is another step closer to completion with the recent assembly of the support structure's wings.
