Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September ...
NASA develops process to create very accurate eclipse maps
New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the moon's shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers ...

Could interstellar quantum communications involve Earth or solve the Fermi paradox?
Thus far, the search for extraterrestrial intelligence (SETI) has used strategies based on classical science—listening for radio waves, telescopes watching for optical signals, telescopes in orbit scouring light from the ...
Artemis I mission data show astronauts sent to the moon aboard Orion will be protected from radiation
According to a large team of technical and health specialists, astronauts aboard the Orion spacecraft will be well protected from radiation when the Artemis II mission travels to the moon and back next year.
Astronomers can't agree on how fast the universe is expanding. New approaches aim to break the impasse
It is almost 100 years since scientists discovered the universe is expanding. In the decades that followed, the accuracy of the measurements, and interpretations and implications of this discovery, were a source of fierce ...

Detailed model suggests organic matter on Mars was formed from atmospheric formaldehyde
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually life. In their quest to answer the burning ...

Astronomers detect hundreds of supernova remnants using novel method
Using a new method exploiting the capabilities of the Multi Unit Spectroscopic Explorer (MUSE), astronomers have detected 307 new supernova remnants, including seven rare oxygen-rich ones. The finding was presented in a research ...
Magnifying deep space through the 'Carousel Lens'—rare alignment offers unique opportunity to study cosmology
In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational ...
