The behaviour of one of nature's humblest creatures and archival data from the NASA/ESA Hubble Space Telescope are helping astronomers probe the largest structures in the Universe.
Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water.
A star of about eight percent the Sun's mass has been caught emitting an enormous 'super flare' of X-rays – a dramatic high-energy eruption that poses a fundamental problem for astronomers, who did not think it possible on stars that small.
ESA's exoplanet-observer CHEOPS acquired the first image of its initial target star, following the successful telescope cover opening on 29 January 2020.
A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.
The novel coronavirus COVID-19 is causing significant impact and disruption on the worldwide community. Given those circumstances, STScI, NASA, ESA, and CSA have taken the decision to delay the proposal deadline for JWST Cycle 1 General Observer (GO) proposals to no earlier than 27 May 2020.
Proposals are solicited for observations with INTEGRAL in response to the Eighteenth Announcement of Opportunity, AO-18, issued 2 March 2020. This AO covers the period January to December 2021. The deadline for proposals has been postponed to 4 May, 14:00 CEST.
