Proposals are solicited in response to the second Announcement of Opportunity (AO-2) for observing time in the CHEOPS Guest Observers Programme. This AO covers the period 26 March 2021 to 25 March 2022. The deadline for proposals is 1 December 2020, 13:00 CET/12:00 GMT.
Using data from the international Cassini-Huygens mission to Saturn and Titan, scientists have found that there are two distinct types of craters on Saturn's largest moon Titan that are still being shaped by erosion.
After years of detective work, the second touchdown site of Rosetta's Philae lander has been located on Comet 67P/Churyumov-Gerasimenko in a site that resembles the shape of a skull. Philae left its imprint in billions-of-years-old ice, revealing that the comet's icy interior is softer than cappuccino froth.
The ESA-JAXA BepiColombo mission has completed the first of two Venus flybys needed to set it on course with the Solar System's innermost planet, Mercury.
The European Space Agency (ESA) and the Japanese Aerospace Exploration Agency's Institute of Space and Astronautical Science (ISAS/JAXA) have announced their decision to no longer consider the infrared space observatory, SPICA, as a candidate for the upcoming selection as ESA's 5th medium-class mission in its Cosmic Vision...
ESA's Science Programme Committee has confirmed the continued operations of five missions led by ESA's Science Programme: Cluster, Gaia, INTEGRAL, Mars Express, and XMM-Newton, from 1 January 2021 to 31 December 2022. The SPC also confirmed the Science Programme's contributions to the extended operations of Hinode, Hubble Space Telescope,...
The NASA/ESA's Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away. Supernovae like this one can be used as cosmic tape measures, allowing astronomers to calculate the distance to their galaxies.
ESA has released its first Solar Orbiter data to the scientific community and the wider public. The instruments contributing to this data release come from the suite of in-situ instruments that measure the conditions surrounding the spacecraft.
ESA's Rosetta mission has revealed a unique kind of aurora, an exciting phenomenon seen throughout the Solar System, at its target comet, Comet 67P/Churyumov-Gerasimenko.
This latest image of Jupiter, taken by the NASA/ESA Hubble Space Telescope on 25 August 2020, was captured when the planet was 653 million kilometres from Earth.
Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves.
The NASA/ESA Hubble Space Telescope has captured the closest images yet of the sky's latest visitor to make the headlines, comet C/2020 F3 NEOWISE, after it passed by the Sun. The new images of the comet were taken on 8 August and feature the visitor's coma, the fine shell that surrounds its nucleus, and its dusty output.
Proposals are solicited for observations with XMM-Newton in response to the twentieth Announcement of Opportunity, AO-20, issued 18 August 2020. This AO covers the period May 2021 to April 2022 and is open to proposers from all over the world. The deadline for proposal submission is 9 October 2020, 12:00 UTC.
New observations by the NASA/ESA Hubble Space Telescope suggest that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse's surface.
Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth's atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life.
New research using data from multiple spacecraft, including ESA's Cluster mission, has revealed the cause behind the sudden brightening of the auroral oval before it breaks up into a substorm.
A global collaboration of telescopes including ESA's INTEGRAL high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy – something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery.
Proposals are invited for the CHEOPS Discretionary Programme, an element of the Guest Observers Programme which enables scientists to propose observations of individual targets that have been discovered, or declared to be of high scientific merit, since the close of AO-1 back in mid-May 2019.
The launch of the NASA/ESA/CSA James Webb Space Telescope (Webb) on an Ariane 5 rocket from Europe's Spaceport in French Guiana is now planned for 31 October 2021.
The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed 'campfires', near the surface of our closest star.
