"There are many interesting rock and mineral outcrops on Mars where we would like to search for fossils, but since we can't send rovers to all of them we have tried to prioritise the most promising deposits based on the... Continue reading

The presence of microbial life in Earth's stratosphere is not only opening up a new arena in which to study extremophiles, but is increasing the range of possible environments in which we may find life on other planets. The stratosphere... Continue reading

“A lot of people have focused quite intensively on trying to understand what went extinct [at the end of the Cretaceous],” says Daniel Field, from the University of Bath. “But we know very little about how or why birds managed... Continue reading

On NASA's new Exoplanet Exploration website, you can explore an imagined surface of an alien world via 360-degree, interactive visualizations. As you investigate each planet's surface, you'll discover fascinating features, like the blood-red sky of TRAPPIST-1d, or stand on a... Continue reading

It's no secret that the Milky Way is huge, long thought to be about 100,000 light-years end to end with about 200 billion stars and their orbiting planets, but new research shows that it may be much bigger than we... Continue reading

"If the Martian crustal dichotomy formed as a result of a giant impact, and available data and modeling suggest this is likely, the history of NWA 7034 requires that it formed very early in the planet's history, before 4.4 billion... Continue reading

Our orbit through the Milky Way is not a perfect circle or an ellipse, since the galaxy itself is a landscape of undulating concentrations of mass and complex gravitational fields. As Caleb Scharf observes in The Copernicus Complex, "none of... Continue reading

"Most theories of human evolution give the impression that humans are markedly distinct from apes anatomically, but these are unverifiable 'just-so stories'. The real evidence shows we are not so different overall. This study highlights that a thorough knowledge of... Continue reading

A team of astronomers has performed one of the highest resolution observations in astronomical history by observing two intense regions of radiation, 20 kilometers apart, around a star 6500 light-years away. The observation is equivalent to using a telescope on... Continue reading

“It has a real magnetism to it,” said Gregory Laughlin, an astronomer at Yale University. “I mean, finding a 10-Earth-mass planet in our own solar system would be a discovery of unrivaled scientific magnitude.” In early 2016, two planetary scientists... Continue reading

Dark galaxies are essentially devoid of stars, therefore they don’t emit any light that telescopes can catch. This makes them virtually impossible to observe unless they are illuminated by an external light source like a background quasar. The gargantuan quasar... Continue reading

A squad of seals living off the coast of West Antarctica has provided scientists with data that could help to improve estimates of future sea-level rise. Researchers equipped the rolly-poly marine mammals with sensors that measured temperature and salinity in... Continue reading

An Antares rocket launched from Virginia this morning includes the Cold Atom Laboratory (CAL) that will chill atoms to just about absolute zero—colder than the vacuum of space itself, creating Bose-Einstein condensates on board the ISS. “Essentially, it’s going to... Continue reading

The Square Kilometer Array, which will be the widest radio telescope array when it opens and one of the most precise when it begins operation in 2020, combining 250 dishes. "This next-generation facility will be the first telescope capable of... Continue reading

For now, scientists in Hawaii and around the world are watching Kilauea and waiting to see what else the volcano will do. “This has so far been playing out how USGS said it would,” says Janine Krippner, a volcanologist at... Continue reading

China has taken its first major step in a groundbreaking lunar mission. On 21 May, a probe launched from Xichang Space Centre to head beyond the Moon — where it will lie ready to act as a communications station for... Continue reading

If intelligent life re-emerges in our solar system in a few billion years, observes B. G. Buehler, only a few points of light will still be visible in the sky. What kind of theory of the universe will those beings... Continue reading

"Asteroid immigration from other star systems occurs because the Sun initially formed in a tightly-packed star cluster, where every star had its own system of planets and asteroids," says Dr. Helena Morais, an astronomer with São Paulo State University. "How... Continue reading

“The signals will be from the civilization as it was,” said Frank Drake, creator of the famous Drake Equation. “It is not a remote possibility — it is a high probability — that signals we receive will be from a... Continue reading

"We learned from Kepler that there are more planets than stars in our sky, and now TESS will open our eyes to the variety of planets around some of the closest stars," Paul Hertz, the director of NASA's astrophysics division,... Continue reading

"What made this even worse, was that every move had to be done by remote control with a nine-hour round-trip radio communication time between mission control and the spacecraft. Science classes teach how the speed of light is incredibly fast,... Continue reading

“It takes little imagination to consider that the pre-Cambrian mass extinction event(s) was correlated with the impact of a giant life-bearing comet (or comets), and the subsequent seeding of Earth with new cosmic-derived cellular organisms and viral genes,” that hitched... Continue reading

"What we are witnessing is major hydrologic change," said co-author Jay Famiglietti of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. "We see a distinctive pattern of the wet land areas of the world getting wetter - those are the... Continue reading

New data shows that the Ant Nebula beams intense laser emission from its core. Lasers are well-known down on earth in everyday life, from special visual effects in music concerts to health care and communications. In space, laser emission is... Continue reading

"With this discovery we managed to reach the earliest phase of cosmic star formation history," said Takuya Hashimoto, a researcher at Osaka Sangyo University and the National Astronomical Observatory of Japan. "We are eager to find oxygen in even farther... Continue reading
