NASA's Goddard Space Flight Center 3 May 2019, 11:35 UTC Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes — especially when viewed through a telescope such as the NASA/ESA Hubble Space Telescope. In fact, this image from Hubble frames a perfect spiral specimen: the stunning NGC 2903.

ESO Top News 2 May 2019, 13:00 UTC This image, a composite of several observations captured by ESO’s VLT Survey Telescope (VST), shows the ESA spacecraft Gaia as a faint trail of dots across the lower half of the star-filled field of view. These observations were taken as part of an ongoing collaborative effort to measure Gaia’s orbit and improve the accuracy of its unprecedented star map.
MIT 2 May 2019, 12:00 UTC On April 25, 2019, the National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears likely to be a crash between two neutron stars — the dense remnants of massive stars that previously exploded. One day later, on April 26, the LIGO-Virgo network spotted another candidate source with a potentially interesting twist: It may in fact have resulted from the collision of a neutron star and black hole, an event never before witnessed.
NASA's Jet Propulsion Laboratory News and Features 1 May 2019, 15:44 UTC NASA's InSight lander captured a series of sunrise and sunset images. A camera on the spacecraft's robotic arm snapped the photos on April 24 and 25, the 145th Martian day, or sol, of the mission. In local Mars time, the shots were taken starting around 5:30 a.m. and then again starting around 6:30 p.m. As a bonus, a camera under the lander's deck also caught clouds drifting across the Martian sky at sunset.
ESA Top News 1 May 2019, 10:18 UTC Our protective magnetic field is always restless, but every now and then something weird happens – it jerks. Although scientists have known about these rapid shifts for some 40 years, the reason why they occur has remained a frustrating mystery, until now.
Harvard-Smithsonian Center for Astrophysics 30 Apr 2019, 15:09 UTC The Smithsonian today made available a new online interactive that allows users to explore a three-dimensional (3D) visualization of the remnants of a supernova, or exploded star.
NASA's Jet Propulsion Laboratory News and Features 29 Apr 2019, 18:29 UTC On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little Dipper. But it won't be a satellite or an airplane - it will be a 1,100-foot-wide (340-meter-wide) near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface. That's within the distance that some of our spacecraft that orbit Earth. The international asteroid research community couldn't be more excited.
