Fig. 1. Night sky centered on the south Galactic pole in a so-called stereographic projection. In this special projection, the Milky Way curves around the…
The Martian South Pole. A new study in Geophysical Research Letters argues there needs to be an underground source of heat for liquid water to…
This week’s Picture of the Week highlights another of the 20 images to come out of ALMA’s first Large Program, the Disk Substructures at High Angular Resolution Project (DSHARP).…
The twin Van Allen Probes have spent more than six years orbiting through Earth’s radiation belts. Orbit changes in early 2019 will ensure that the…
A new, composite image of the Andromeda galaxy made by combining three bands of visible light captured by ZTF. The image covers 2.9 square degrees…
Artist’s concept illustrating Supernova 1987A as the powerful blast wave passes through its outer ring and destroys most of its dust, before the dust re-forms…
Artist impression of Orion Source I, a young, massive star about 1,500 light-years away. New ALMA observations detected a ring of salt — sodium chloride,…
NASA’s Kepler space telescope may be retired, but the discoveries continue to rack up for this historic planet-hunting mission. Kepler rang in the new year…

False-color image of V883 Ori taken with ALMA. The distribution of dust is shown in orange and the distribution of methanol, an organic molecule, is…
This atmospheric image shows a galaxy named Messier 85, captured in all its delicate, hazy glory by the NASA/ESA Hubble Space Telescope. Messier 85 slants…
The stellar wind from a newborn star in the Orion Nebula is preventing more new stars from forming nearby, according to new research using NASA’s…
The wonders – and mysteries – of Kuiper Belt object 2014 MU69 continue to multiply as NASA’s New Horizons spacecraft beams home new images of…
This visualization of a general-relativistic collisionless plasma simulation shows the density of positrons near the event horizon of a rotating black hole. Plasma instabilities produce…
The spiral galaxy D100, on the far right of this Hubble Space Telescope image, is being stripped of its gas as it plunges toward the…
A Hubble image of an ultraluminous infrared galaxy in the relatively nearby universe. Astronomers studying ultraluminous galaxies in the remote, early universe have spotted one…
The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time — around 10,000 years, a blink of an…
Beyond Neptune, there is a large disc of small objects, called the Kuiper Belt and beyond that is the Oort cloud, home of the comets.…
The Hubble Ultra Deep Field of galaxies. A new study of the star formation activity in 179 of the galaxies in this image including many…
