Operations underway to restore payload computer on Hubble Space Telescope
Thursday, 15 July 2021 00:50
NASA has identified the possible cause of the payload computer problem that suspended Hubble Space Telescope science operations on June 13. The telescope itself and science instruments remain healthy and in a safe configuration.
The payload computer resides in the Science Instrument Command and Data Handling (SI C&DH) unit. It controls, coordinates, and monitors Hubble's science instrument LCO discovers activity on largest comet ever found

A newly discovered visitor to the outer edges of our Solar System has been shown to be the largest known comet ever, thanks to the rapid response telescopes of Las Cumbres Observatory. The object, which is named Comet C/2014 UN271 Bernardinelli-Bernstein after its two discoverers, was first announced on Saturday, June 19th, 2021.
C/2014 UN271 was found by reprocessing four years of data fr A potential new tracer of exoplanet formation

An international team of astronomers, including scientists from the Max Planck Institute for Astronomy, have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b at a distance of 300 light-years in the constellation Musca (Fly).

Dr. Iair Arcavi, a Tel Aviv University researcher at the Raymond and Beverly Sackler Faculty of Exact Sciences, participated in a study that discovered a new type of stellar explosion - an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. Such supernovas arise from the explosions of stars 8-9 times the mass of the sun.

NASA, European Space Agency join forces on climate change
Wednesday, 14 July 2021 07:18
NASA and the European Space Agency joined forces Tuesday in the battle against climate change, a move they said paves the way to a global response to the problem.
"To ensure that data from Earth-observing satellites are used to their best advantage, further science and, ultimately, bring the most benefit to humankind, ESA and NASA have formed a strategic partnership for Earth science and climate change," ESA said in a statement.
The partnership was formalised on Tuesday with a statement of intent signed by ESA's Director General Josef Aschbacher and NASA's Administrator Bill Nelson.
This aims "to pave the way to leading a global response to climate change, through the monitoring of the Earth and its environment with their combined efforts in Earth science observations, research and applications," the statement said.
The US and European space agencies have already worked together on environmental issues, notably on the Copernicus Sentinel-6 programme in which satellites about the size and shape of a large minivan measure sea level rise, tracking changes threatening to disrupt tens of millions of lives within a generation.
