When lockdowns during the coronavirus pandemic cut local nitrogen oxide emissions, the effect on ozone pollution was global and unexpectedly rapid.
NASA’s Nancy Grace Roman Space Telescope team recently approved all 24 of the detectors the mission needs. These devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky.
Measuring the polarization of scattered sunlight lets scientists extrapolate what is in the atmosphere.
The ocean: it's Earth’s largest ecosystem and the habitat for coral – one of the planet’s most unique and oldest life forms.
In a dramatic, multi-staged eruption, the Sun has revealed new clues that could help scientists solve the long-standing mystery of what causes the Sun’s powerful and unpredictable eruptions.
Catch Saturn and Jupiter in the morning, and the constellation Scorpius after dark! Plus skywatchers in the Northeast U.S., Eastern Canada, and Northern Europe can see a partial solar eclipse on June 10th.
New research confirms how particles from space can be sent careening down into Earth’s atmosphere to create the aurora, filling in a missing piece in how this stunning natural phenomenon is generated.
Such detailed maps could help policymakers choose the most effective ways of cutting carbon emissions.
Thirteen scientists working at or affiliated with NASA have been recently named Fellows of the American Astronomical Society (AAS), the major organization of professional astronomers in North America.
The first of the gas-giant orbiter’s back-to-back flybys will provide a close encounter with the massive moon after over 20 years.
The tardigrade, a microscopic animal able to survive in some of the most extreme environments, is being studied aboard the International Space Station to understand how it tolerates prolonged spaceflight and how that knowledge can be used to better protect humans in space.
The universe contains a mind-boggling number of stars – but scientists’ best estimates may be an undercount. A NASA-funded sounding rocket is launching with an improved instrument to look for evidence of extra stars that may have been missed in stellar head counts.
The spacecraft successfully cleared some dust off its solar panels, helping to raise its energy and delay when it will need to switch off its science instruments.
