Using data on a sample of 756 galaxy clusters identified in the Sloan Digital Sky Survey (SDSS), a team of astrophysicists from the United States and Egypt has determined that matter makes up 31% of the total amount of matter and energy in the Universe, with the remainder consisting of dark energy. “To put that [...]

Considering the implications of the reported single spectral line detection of phosphine (PH3) by Greaves et al., we were inspired to re-examine data obtained from the Pioneer-Venus Large Probe Neutral Mass Spectrometer (LNMS) to search for evidence of phosphorus compounds....

Because of its proximity to its parent star, the dayside equilibrium temperature of the ultrahot Jupiter WASP-189b reaches 3,162 degrees Celsius (5,724 degrees Fahrenheit), according to an analysis of data collected by ESA’s CHEOPS (CHaracterising ExOPlanet Satellite) mission. Discovered in 2018, WASP-189b is a gas giant transiting the 730-million-year-old A-type star WASP-189. Also known as [...]

Video: 00:03:10 A European satellite built to carry out precise measurements of sea level changes has arrived in California in preparation for launch. The Sentinel-6 Michael Freilich satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ radar to map sea surface topography. The mission will be used to monitor the height of the sea surface to understand long-term change. It will also measure wave height and wind speed. The satellite will provide fundamental data for climate science, policy-making and protecting the 600 million people who live in vulnerable coastal areas. Data are provided to Copernicus services in near-real time to improve marine and weather forecasts used by maritime and coastal communities.  The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French Space Agency CNES. It is named Michael Freilich after NASA’s former Director of Earth Science and is scheduled for launch on 10 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base. This A-roll contains Copernicus Sentinel-2 images of the Maldives, new in-orbit animations and clean-room footage from testing in Germany.

Planarian flatworms are nature’s versions of Doctor Who, able to regenerate their entire bodies from smaller pieces. This prodigious ability has seen them travel to space, to investigate if the planarians’ regenerative ability is maintained in weightless conditions. Now for the first time an experiment has looked into how the very demanding experience of a rocket launch might impact their possible regrowth, using ESA’s rapidly-spinning Large Diameter Centrifuge to generate hypergravity on the ground.
