A new space telescope named Euclid, an ESA (European Space Agency) mission with important contributions from NASA, is set to launch in July to explore why the universe’s expansion is speeding up. Scientists call the unknown cause of this cosmic acceleration “dark energy.” By May 2027, NASA’s Nancy Grace Roman Space Telescope will join Euclid to explore this puzzle in ways that have never…
The ESA (European Space Agency) and SpaceX are targeting no earlier than 11:11 a.m. EDT (8:11 a.m. PDT) Saturday, July 1, to launch the Euclid spacecraft. Euclid is an ESA mission with contributions from NASA that will shed light on the nature of dark matter and dark energy…
While NASA’s Perseverance rover and Ingenuity helicopter are busy exploring Mars, one-tenth-scale buildable models of them have begun touching down in homes around the globe.
Developed in cooperation with NASA’s Jet Propulsion Laboratory in Southern California, a new…
An international team of researchers has used NASA’s James Webb Space Telescope to calculate the amount of heat energy coming from the rocky exoplanet TRAPPIST-1 c.
The result suggests that the planet’s atmosphere – if it exists at all – is extremely thin.
With a dayside temperature of roughly 380 kelvins (about 225 degrees Fahrenheit), TRAPPIST-1 c is now the coolest rocky exoplanet ever…
NASA’s Jet Propulsion Laboratory is well known for landing rovers on Mars, exploring the solar system with robotic probes, and developing sensitive science instruments that observe Earth and other planets. But less well-known is the lab’s cutting-edge work in the digital…
Using data collected by NASA’s Cassini mission, an international team of scientists has discovered phosphorus – an essential chemical element for life – locked inside salt-rich ice grains ejected into space from Enceladus.
The small moon is known to possess a…
After years of intense drought and diminishing groundwater, California just saw its greatest year-over-year water gains in two decades, according to data from the GRACE-FO (Gravity Recovery and Climate Experiment Follow-On) satellite mission, a partnership between NASA and the German Research Centre for Geosciences (GFZ). This past winter’s bonanza of atmospheric rivers alleviated some of the…
Steps taken by NASA, the agency’s Jet Propulsion Laboratory in Southern California, and Caltech, to put the Psyche mission on track for an October 2023 launch have been outstanding, according to an independently appointed review board. NASA and JPL convened the board last…
Triggered by earthquakes, undersea volcanoes, and other Earth-shaking forces, tsunamis can devastate coastal communities. And when it comes to providing advance warning, every second counts. Scientists at NASA’s Jet Propulsion Laboratory are testing a novel approach to…
Four composite images deliver dazzling views from NASA’s Chandra X-ray Observatory and James Webb Space Telescope of two galaxies, a nebula, and a star cluster. Each image combines Chandra’s X-rays – a form of high-energy light – with infrared data from previously released Webb images, both of which are invisible to the unaided eye. Data from NASA’s Hubble Space Telescope (optical light)…
