ESO Top News 12 Dec 2018, 13:00 UTC While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large Telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.
NASA's Jet Propulsion Laboratory News and Features 11 Dec 2018, 20:12 UTC NASA's InSight lander isn't camera-shy. The spacecraft used a camera on its robotic arm to take its first selfie - a mosaic made up of 11 images. This is the same imaging process used by NASA's Curiosity rover mission, in which many overlapping pictures are taken and later stitched together. Visible in the selfie are the lander's solar panel and its entire deck, including its science instruments.
Carnegie Science 11 Dec 2018, 14:43 UTC New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. Led by Carnegie astronomer Chris Burns, the team’s findings are published in The Astrophysical Journal.
HubbleSite NewsCenter -- Latest News Releases 10 Dec 2018, 21:15 UTC Giacconi leaves a legacy that will endure for generations. The worldwide astronomical community mourns the loss of Riccardo Giacconi, the first permanent director of the Space Telescope Science Institute (STScI) in Baltimore, Maryland.
NASA Breaking News 10 Dec 2018, 17:11 UTC Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Be
NASA Breaking News 10 Dec 2018, 13:00 UTC For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.
ESA Space Science 10 Dec 2018, 08:00 UTC Sometimes it’s all about perspective. This very convincing image of a conjoined moon masquerading as a snowman is actually two separate Saturnian moons – Dione and Rhea – taken from such an angle by the international Cassini spacecraft that they appear as one.
NASA's Goddard Space Flight Center 7 Dec 2018, 16:59 UTC NASA’s James Webb Space Telescope requires a primary mirror so large that it would not fit inside any existing rockets as one single, large mirror. Because of this, Webb is equipped with a revolutionary set of 18 hexagonal mirror segments that are able to fold to fit inside the rocket fairing. Their honeycomb like arrangement allows for Webb to have the largest possible reflective surface area to make observations, with the least amount of dead space in between each.
