What the rise of oxygen on early Earth tells us about life on other planets
When did the Earth reach oxygen levels sufficient to support animal life? Researchers from McGill University have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years. ESA determines new 'space time'
Since November 2021, ESA's satellites and ground stations have been running on a newly defined, incredibly precise "ESOC time". Measured by two atomic clocks in the basement of the ESOC mission control centre in Germany, this new time determination will bring wide-reaching operational benefits for all ESA missions, making new feats possible in space while adding to our global definition of 'now' How NASA in Silicon Valley will use Webb Telescope to study distant worlds
NASA's James Webb Space Telescope is getting ready to give us the best view yet of worlds beyond our own solar system, commonly known as exoplanets. Scientists at NASA's Ames Research Center in California's Silicon Valley will be among the first to observe the cosmos with Webb, and they're looking for clues about how exoplanets form, what they're made of, and whether any could be potentially hab Falcon 9 launches Italian radar satellite

In space race, Europe faces choice: passenger or pilot
As the race to send people to the Moon and beyond heats up, Europe faces calls to make a choice: Keep paying for seats on spacecraft or finally fly its own manned vehicle.
Imagine if Christopher Columbus did not have a ship to sail to the Americas, the head of the European Space Agency said recently, lamenting that the continent lacked a vessel to "explore the next frontier".

While the United States military remains "the best in the world," Department of the Air Force Secretary Frank Kendall said Jan. 19 that the Air and Space Forces must move quickly to adapt and modernize to offset actions by China and others that have dented the "presumption of superiority" held by the U.S.
Kendall offered the assessment during a 45-minute "virtual fireside chat" sponsored b NASA Planes Fly into Snowstorms to Study Snowfall
Scientists repeatedly check the weather forecasts as they prepare aircraft for flight and perform last-minute checks on science instruments. There's a large winter storm rolling in, but that's exactly what these storm-chasing scientists are hoping for.
