The Moon is a pretty inhospitable place for humans but now scientists have figured out a way to get the Oxygen out of its dirt. »
Imagine ponds dotting the floor of Gale Crater, the 100-mile-wide (150-kilometer-wide) ancient basin that Curiosity is exploring. Streams might have laced the crater's walls, running toward its base. »
Researchers investigated the effects of high levels of carbon dioxide on marsh plants. »
Using one cosmic mystery to probe another, astronomers analysed the signal from a fast radio burst to shed light on the diffuse gas in the halo of a massive galaxy. »
This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. »
Deep in the waterlogged peat of salt marshes, carbon is stored at much greater rates than in land ecosystems, serving as an offset to climate change caused by carbon dioxide (CO2) build-up in the atmosphere. »
A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. »
Its size and surface gravity are much larger than Earth’s, and its radiation environment may be hostile, but a distant planet called K2-18b has captured the interest of scientists all over the world. »
Astronomers are studying quasars to see if and how accretion disks are fueled with external mass. »
Pops of bright blue and green in this image of the Fireworks galaxy (NGC 6946) show the locations of extremely bright sources of X-ray light captured by NASA's NuSTAR space observatory. »
Researchers discovered two Earth-like planets near Teegarden’s Star. »
New image from the NASA/ESA Hubble Space Telescope shows NGC 5307, a planetary nebula that lies about 10,000 light-years from Earth. »
A new study indicates that some exoplanets may have better conditions for life to thrive than Earth itself has. »
A new study using data from NASA's Spitzer Space Telescope provides a rare glimpse of conditions on the surface of a rocky planet orbiting a star beyond the Sun. »
Earth’s Moon and Mercury, the closest planet to the Sun, may contain significantly more water ice than previously thought, according to a new analysis. »
A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star’s habitable zone. If made of rock, this planet may be around twice Earth’s size. »
Observations by NASA's Hubble Space Telescope reveal magnesium and iron gas streaming from the strange world outside our solar system known as WASP-121b. »
The first known interstellar object to visit our solar system was discovered on Oct. 19, 2017, by the Panoramic Survey Telescope and Rapid Response System 1 Telescope located at the University of Hawaii’s Haleakala Observatory. »
New data from the Keck Observatory show gas directly spiraling into growing galaxies. »
As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away. »
Two NASA space telescopes have teamed up to identify, for the first time, the detailed chemical "fingerprint" of a planet between the sizes of Earth and Neptune. No planets like this can be found in our own solar system, but they are common around other stars. »
This week, NASA's Curiosity Mars rover found a surprising result: the largest amount of methane ever measured during the mission - about 21 parts per billion units by volume (ppbv). One ppbv means that if you take a volume of air on Mars, one billionth of the volume of air is methane. »

An oxygen generator is designed to convert carbon dioxide into breathable oxygen. »
Curiosity rover has confirmed that the region on Mars it's exploring, called the "clay-bearing unit," is well deserving of its name. »
An international group of astronomers has identified a rogue planet orbiting its star in the so-called Neptunian Desert. »
German Planetologists showed for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago. »
NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds. »
A survey of more than 12,000 images reveals that at least one lunar mare has been cracking and shifting as much as other parts of the Moon - and may even be doing so today. The study adds to a growing understanding that the Moon is an actively changing world. »
The Event Horizon Telescope unveiled the first-ever image of a black hole's event horizon, the area beyond which light cannot escape the immense gravity of the black hole. That giant black hole, with a mass of 6.5 billion Suns, is located in the elliptical galaxy Messier 87. »
NASA's Mars InSight lander has measured and recorded for the first time ever a likely "marsquake." »
Scientists from NASA’s Goddard Space Flight Center in Greenbelt, Maryland have found evidence that Mercury’s inner core is indeed solid and that it is very nearly the same size as Earth’s inner core. »
On its final flyby of Saturn's largest moon, NASA's Cassini spacecraft gathered radar data revealing that the small liquid lakes in Titan's northern hemisphere are surprisingly deep, perched atop hills and filled with methane. »
Researchers from NASA and the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, report that streams of meteoroids striking the Moon infuse the thin lunar atmosphere with a short-lived water vapor. »
New Earth-based telescope observations show that auroras at Jupiter's poles are heating the planet's atmosphere to a greater depth than previously thought - and that it is a rapid response to the solar wind. »
