Data from NASA’s WISE mission have led to the discovery of two clusters of newborn stars thousands of light-years below the plane of our galaxy.

The scientists not only found giant molecular clouds thousands of light-years above and below the galactic disk, but also one of them unexpectedly contained two clusters of stars.

NGC2276-3c has traits similar to both stellar-mass and supermassive black holes.

Like a cowboy at a rodeo, NASA’s newest Earth-observing satellite, the Soil Moisture Active Passive (SMAP), has triumphantly raised its “arm” and unfurled a huge golden “lasso” (antenna).

Four new NASA Earth-observing missions are collecting data from space – with a fifth newly in orbit – after the busiest year of NASA Earth science launches in more than a decade.

A new study of Earth’s ionosphere, a part of the upper atmosphere, could have applications for better GPS communications.

Join us Friday, 27 February, at 10:00 CET for the ‘Earth from Space’ video programme. This week features a false-colour image of Brussels

This is most likely due to dense areas of dust and gas that shield molecules from otherwise lethal radiation.

This may be pointing to a volcano-like origin of the spots, but Dawn scientists will wait for better resolution to make geologic interpretations.

Think of it as the ultimate hitchhiking opportunity: ESA is offering CubeSats a ride to a pair of asteroids in deep space.

Dwarf planet Ceres continues to puzzle scientists as NASA’s Dawn spacecraft gets closer to being captured into orbit around the object.

Sample-collection drilling that NASA’s Curiosity Mars rover completed Tuesday will likely be the last before the rover departs “Pahrump Hills.”

At a distance of 12.8 billion light-years from Earth, this quasar was formed only 900 million years after the Big Bang.

Scientists propose that the matter-antimatter asymmetry could be related to the Higgs boson particle.

Key science elements of the James Webb Space Telescope have been upgraded ahead of the observatory’s launch in 2018.

Technology image of the week: Through daily software uploads, this miniature satellite will be a testbed for innovative control methods

JPL will host a briefing Monday, March 2, about the March 6 arrival of NASA’s Dawn spacecraft at the dwarf planet Ceres. The event will be carried live on NASA TV and online.

NASA’s Curiosity Mars rover used the camera on its robotic arm to record the pieces of a portrait that shows the rover within a panorama of the area it is studying.

Mission controllers at JPL today sent commands to unfurl the reflector antenna on NASA’s new Soil Moisture Active Passive (SMAP) observatory, launched Jan. 31.

ESA’s IXV spaceplane, launched on a Vega rocket on 11 February, is now on its way to Europe for detailed study in Italy.

Human spaceflight and operations image of the week: Human endothelial cells and nuclei stained and exposed under a microscope in preparation for space

Before Sentinel-2A is packed up and shipped to French Guiana for its launch targeted on 12 June, media representatives and specialists got one last look at the second satellite for Europe’s Copernicus programme.

Emergency services rescued 1780 people in the Austrian Alps last year. They can now count on satellites to access maps, send messages, give warnings and stay in contact.

Research shows that under a crystalline crust should still be very cold and contain more porous amorphous ice.

Over the past 12 months NASA has added five missions to its orbiting Earth-observing fleet. NASA scientists will share early observations during a media telecon Feb. 26.

In Antarctica, the crew of the French–Italian Concordia research station are preparing for the winter. They have to survive six months of complete isolation – four in darkness because the Sun never rises above the horizon – while they perform science in one of the most barren places on Earth.

A university professor concludes that movement through dark matter may perturb the orbits of comets and lead to additional heating in Earth’s core, both of which could be connected with mass extinction events.

Space Science Image of the Week: Herschel and Spitzer team up to explore the Small Magellanic Cloud, one of our nearest extragalactic neighbours

Our week through the lens: 16-20 February 2015

The new images reveal the inner disk around Beta Pictoris and confirm structures predicted by computer simulations.

Thirteen-year-old Julia Derzay of Pewaukee, Wisconsin, wins a trip to the Northeast Astronomy Forum & Telescope Show with her entry for Astronomy’s 2015 Youth Essay Contest.

This discovery that the winds blow in all directions has given astronomers their first opportunity to measure the strength of these ultra-fast winds and prove they are powerful enough to inhibit the host galaxy’s ability to make new stars.

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspec…

Following the initial selection in 2013 for Biomass to become ESA’s seventh Earth Explorer mission and the completion of preparatory activities, ESA Member States yesterday gave the green light for its full implementation for launch in 2020.

Join us Friday, 20 February, at 10:00 CET for the ‘Earth from Space’ video programme. This week features a Sentinel-1A mosaic of Estonia

Astronomers have identified the closest known flyby of a star to our solar system.

Astronomers have identified the closest known flyby of a star to our solar system.

There seems to be a mysterious link between the amount of dark matter a galaxy holds and the size of its central black hole.

A complex network of isolated hills, ridges and small basins spanning 1400 km on Mars is thought to hide large quantities of water-ice.

Wishing the world’s Chinese population safe travels for their celebrations of the year of the sheep

The instrument has been used to search for a brown dwarf expected to be orbiting the unusual double star V471 Tauri — and found nothing.

As the spacecraft delivers better images and other data, the science team will be investigating the nature and composition of the dwarf planet.
