Alan McStravick for redOrbit.com - Your Universe Online The European Space Agency (ESA) has recently announced the successful on-Earth testing of its Solar Orbiter's protective heat shield. The test, conducted at the ESA's Technical Center in Noordwijk subjected a 'structural-thermal' version of the craft's sunshield to an artificial Sun for a period of two weeks in their vacuum chamber - the largest in Europe. The results prove the shield will have no issue with the extreme temperatures...

April Flowers for redOrbit.com - Your Universe Online In a new study called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project, the most comprehensive and colorful picture of the evolving universe has been captured by astronomers using the Hubble Space Telescope. Prior to the UVUDF study, astronomers knew a great deal about star formation that occurred in nearby galaxies, thanks to UV telescopes such as NASA's GALEX observatory. The astronomers were also able to...

Serpens Cloud Core Hatches New Stars

By Whitney Clavin, NASA's Jet Propulsion Laboratory Stars that are just beginning to coalesce out of cool swaths of dust and gas are showcased in this image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). Infrared light has been assigned colors we see with our eyes, revealing young stars in orange and yellow, and a central parcel of gas in blue. This area is hidden in visible-light views, but infrared light can travel through the dust, offering a peek inside...

redOrbit Staff & Wire Reports - Your Universe Online Believed to be retired for good after breaking down last year, the Kepler spacecraft has been revived and will be part of a newly-approved NASA mission to seek out new exoplanets while also expanding its role into the realm of astrophysical observations, the US space agency revealed on Friday. “The team received good news from NASA HQ – the K2 mission, the two-wheel operation mode of the Kepler spacecraft observing in the...

ESA’s New X-ray Optics To Observe The Hot Universe
2014-05-16 03:41:51

ESA A new idea to use super-polished silicon wafers as the heart of a telescope is set to reveal more of the hot, high-energy Universe, peering back into its turbulent history. Invisible X-rays tell us about the very hot matter in the Universe – black holes, supernovas and superheated gas clouds. Today’s X-ray observatories, ESA’s XMM-Newton and NASA’s Chandra, were launched in the last century, and are still delivering world-class science. But they are starting to age. To...

New Insight Into Formation Of Star Clusters Provided By NASA's Chandra X-ray Observatory
2014-05-16 03:44:41

[ Watch The Video: A Tour Of The Flame Nebula ] Harvard-Smithsonian Center for Astrophysics Stars are often born in clusters, in giant clouds of gas and dust. Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work. This composite image shows one of the clusters, NGC 2024, which is found in the center of the so-called Flame Nebula about 1,400...

A Look At The Amazing Statistics As NASA's Hubble Space Telescope Enters Its 25th Year
2014-05-12 03:59:55

[ Hubble Videos ] Rob Gutro, NASA On April 24, 1990, the space shuttle Discovery lifted off from Earth with the Hubble Space Telescope nestled securely in its bay. The following day, Hubble was released into space, ready to peer into the vast unknown of space. NASA's Hubble Space Telescope recently marked its 24th year in space and to celebrate its 25th year, NASA is taking a look at some of the amazing statistics generated by the world-famous telescope. Hubble has...

Gamma-ray Burst

redOrbit Staff & Wire Reports - Your Universe Online An international team of astronomers has for the first time measured circular polarization in the afterglow of gamma-ray bursts, the powerful flashes of radiation originating from massive dying stars as they collapse into black holes. A massive star explodes as a supernova when it dies, and its core collapses into a black hole, scientists from the Niels Bohr Institute explained in a statement Wednesday. In rare instances, a jet is...

NASA NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole. Images from the space telescopes also pinpointed the object's distance to 7.2 light-years away, earning it the title for fourth closest system to our sun. The closest system, a trio of stars, is Alpha Centauri, at about 4 light-years away. "It's very...

J.D. Harrington, NASA Astronomers using NASA's Hubble Space Telescope have applied a new image processing technique to obtain near-infrared scattered light photos of five disks observed around young stars in the Mikulski Archive for Space Telescopes database. These disks are telltale evidence for newly formed planets. If astronomers initially miss something in their review of data, they can make new discoveries by revisiting earlier data with new image processing techniques, thanks to...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
