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.

A Moon-scanning method that can automatically classify important lunar features from telescope images could significantly improve the efficiency of selecting sites for exploration.
There is more than meets the eye to picking a landing or exploration site on the Moon. The visible area of the lunar surface is larger than Russia and is pockmarked by thousands of craters and crisscrossed by ca The mystery of what causes Jupiter's X-ray auroras is solved
Wednesday, 14 July 2021 05:23
The 40-year-old mystery of what causes Jupiter's X-ray auroras has been solved. For the first time, astronomers have seen the entire mechanism at work - and it could be a process occurring in many other parts of the Universe too.
Planetary astronomers have studied Jupiter's spectacular X-ray auroral emission for decades. The X-ray 'colours' of these auroras show that they are triggered by Nanosatellites could play pivotal role in defense against enemy missiles
