Astronomers using ESO’s Very Large Telescope (VLT) have captured a beautiful image of a planetary nebula called the Skull Nebula.
This image, taken by...
A ferric mineral called hematite (Fe2O3) is present at high latitudes on the Moon, mostly associated with east- and equator-facing sides of topographic...
Using data from the NOMAD (Nadir and Occultation for Mars Discovery) ultraviolet and visible spectrometer instrument on board ESA’s ExoMars Trace Gas...
Using data from the Sample Analysis at Mars (SAM) instrument on NASA’s rover Curiosity, researchers have found that certain minerals in rocks at Gale...
The surface of Earth was likely covered by a global ocean 3.24 billion years ago (Archean Eon), according to a new study published in the journal Nature...
An international team of biologists has discovered that a tiny parasite of salmon called Henneguya salminicola has no mitochondrial genome and thus has...
Named the auroral dunes, the phenomenon was discovered by citizen scientists in Finland; it occurs at a relatively low altitude of 100 km (62 miles), in...
Using high-resolution spectroscopic observations from the High-Resolution Echelle Spectrometer (HIRES) on the 10-m Keck I telescope at the W. M. Keck Observatory,...
Since exoplanets are so far away, astronomers cannot look for signs of extraterrestrial life by visiting these distant worlds. Instead, they must use a...
The existence of habitable alien worlds has been a mainstay of popular culture for more than a century. In the 19th century, astronomers believed that...
A Neptune-like exoplanet orbits an Earth-sized white dwarf star called WD J091405.30+191412.25 (WD J0914 for short) once every 10 days, leaving a comet-like...
There isn’t a strong correlation between gas giant and host star compositions when it comes to elements heavier than hydrogen and helium, according to...
The Sample Analysis at Mars (SAM) instrument onboard NASA’s Curiosity rover has measured the seasonal changes in the gases that fill the air directly...
White dwarfs are dense, burned-out remnants of normal stars. Due to their strong gravitational pull, surface atmospheres of these ancient objects should...
Saturn’s moon Enceladus is erupting a plume of gas and ice grains from its south pole. According to new research using data from NASA’s Cassini mission,...
The blue-banded sea snake (Hydrophis cyanocinctus) uses a complex system of large blood vessels in its head to draw in extra oxygen when it dives and swims...
A team of researchers from Rensselaer Polytechnic Institute and the University of Texas Austin has used a new technique to analyze tiny amounts of gas...
