The crisis over Russia's Ukrainian aggression presents NASA and other space agencies with the most serious diplomatic strain in the 22-year history of the International Space Station partnership, experts said. Russia is a major partner with the United States, Europe, Japan and Canada in the space station's maintenance and operation. Russia provides critical cargo and crew transport,

This image from ESA’s Mars Express shows part of possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation, or MFF.

The NIRSpec instrument is the workhorse near-infrared spectrograph on board the James Webb Space Telescope and is provided by ESA.

NIRSpec will allow scientists to study objects embedded in shrouds of gas and dust, to find out more about how galaxies formed and evolved, and to characterise the atmospheres of exoplanet to determine if water is present.

The primary goal of NIRSpec is to enable large spectroscopic surveys of astronomical objects like stars or distant galaxies. This is made possible by its powerful multi-object spectroscopy mode, which will make use of use of roughly a quarter of a

Our galaxy is a giant 'smoothie' of blended stars and gas but a new study tells us where the components came from. In its early days, the Milky Way was like a giant smoothie, as if galaxies consisting of billions of stars, and an enormous amount of gas had been thrown together into a gigantic blender. But a new study picks apart this mixture by analysing individual stars to identify which origin

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143. The pair contains the glittery, distorted, star-forming spiral galaxy NGC 2445 at right, along with its less flashy companion, NGC 2444 at left. Astronomers s

A rare exoplanet which orbits around two stars at once has been detected using a ground-based telescope by a team led by the University of Birmingham. The planet, called Kepler-16b, has so far only been seen using the Kepler space telescope. It orbits around two stars, with the two orbits also orbiting one another, forming a binary star system. Kepler-16b is located some 245 light years fr

Despite being close to Earth and having nearly the same size, Venus is another world. Underneath its thick mantle of acid sulfuric clouds, at the surface 460 degrees Celsius are the rule. This temperature is kept by the greenhouse effect of a virtually carbon dioxide only atmosphere. Seventy kilometres above, one has to withstand a perpetual wind storm, the product of the so called Venus superro

Newspapers around the world printed the discovery on their front pages: Astronomers had found that a red dwarf star called TRAPPIST-1 was home to a close-knit family of seven Earth-size planets. NASA announced the system Feb. 22, 2017. Using telescopes on the ground and in space, scientists revealed one of the most unusual planetary systems yet found beyond our Sun and opened the tantalizi

MSL planning was met with beautiful images of our path ahead, like this one. We ended up planning to look at many of these rocks with our science instruments before driving on. This is a busy plan, covering four sols due to the holiday on Monday. In order to keep things manageable, especially given that our uplink is early tonight, we are doing all of our activities on the last 3 sols of the pla
