Planetary scientist Christopher Edwards and his team will use renewed NASA funding for Mars Science Lab Curiosity Rover project to continue exploring the rock record on the Red Planet.
When the European Space Agency’s Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a comet emit oxygen, let alone in such abundance. But most alarming were the deeper implications: that researchers had to account for so much oxygen, which meant reconsidering everything they thought they already knew about the chemistry of the early solar system and how it formed. A new analysis, however, led by planetary scientist Adrienn Luspay-Kuti at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, shows Rosetta’s discovery may not be as strange as scientists first imagined.

The Dark Energy Spectroscopic Instrument (DESI) has cataloged more galaxies than all other previous three-dimensional redshift surveys combined, measuring 7.5 million galaxies in only seven months since beginning science operations. The US Department of Energy's Lawrence Berkeley National Laboratory leads DESI, which is installed at Kitt Peak National Observatory, a program of NSF's NOIRLab, on the Nicholas U. Mayall 4-meter Telescope.
Scientists are closer to solving a solar heating puzzle using direct data now that NASA’s Parker Solar Probe (PSP), on which The University of Alabama in Huntsville (UAH) teamed to develop an instrument suite to directly measure particles from the solar wind, has for the first time entered a region never before explored.
Astronomers using Hubble and radio telescopes have found increasing evidence that the black hole near the center of our Milky Way galaxy periodically awakens, captures a star or gas cloud that falls into it, and then releases powerful beams of radiation and particles.
This ethereal image, captured from Chile by the international Gemini Observatory, a Program of NSF's NOIRLab, looks as delicate as a butterfly’s wing. It is, however, a structure known as the Chamaeleon Infrared Nebula, which is located near the center of the mammoth Chamaeleon I dark cloud, one of the nearest star-forming regions in our Milky Way.
The Hubble Space Telescope is taking us on the scenic route through the outer Solar System with crisp new images of the gas giants—Jupiter, Saturn, Uranus, and Neptune.

New calculations show that a black hole slurping down a star may not have generated enough energy to launch a neutrino.
Since the Perseverance rover landed in Jezero crater on Mars in February, the rover and its team of scientists back on Earth have been hard at work exploring the floor of the crater that once held an ancient lake.
Considered an ultra-hot Jupiter – a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain – the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists had realized.
While black holes and toddlers don't seem to have much in common, they are remarkably similar in one aspect: Both are messy eaters, generating ample evidence that a meal has taken place.
A series of new images reveals that planets form in organic soups — and no two soups are alike.

Watching X-rays flung out into the universe by the supermassive black hole at the center of a galaxy 800 million light-years away, Stanford University astrophysicist Dan Wilkins noticed an intriguing pattern.
Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a Program of NSF’s NOIRLab, astronomers identified the cause of this 0.6-second flurry of gamma rays as a supernova explosion in a distant galaxy. GRBs caused by supernovae are usually more than twice as long, which suggests that some short GRBs might actually be imposters — supernova-produced GRBs in disguise.
A co-investigator on NASA’s Juno mission to Jupiter, Prof. Yohai Kaspi and his team have made discoveries about the gas giant’s climate: Each pole has several Australia-sized cyclones that rarely change their size, number, or position because massive polar storms keep them at bay, and strong jet streams won’t let them form below a certain latitude.
Astronomers have imaged the heart of Centaurus A in unprecedented detail and pinpointed the galaxy’s central supermassive black hole, revealing how a gigantic jet is born. Most remarkably, only the outer edges of the jet seem to emit radiation, which challenges current theoretical models of jets.

An investigation carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC) ?ofia Chrobáková, a doctoral student at the IAC and the University of La Laguna (ULL), and Martín López Corredoira, questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in the axis of rotation of the disc warp is incorrect.
Astronomers are on the trail of one of the universe's most enigmatic events: powerful bursts of radio waves that disappear in the blink of an eye. Using Hubble, they have traced the radio bursts to the spiral arms of distant galaxies.
In 2018, astronomers announced that they had discovered an exoplanet orbiting Barnard’s star, our solar system’s second-closest stellar neighbor, but further analysis by an international group of researchers headed by a graduate student at the University of California, Irvine has cast doubt on the finding.
Astronomers have found two close pairs of quasars in the distant Universe. Follow-up observations with Gemini North spectroscopically resolved one of the distant quasar pairs, after their discovery with the Hubble Space Telescope and Gaia spacecraft. These quasars are closer together than any pair of quasars found so far away, providing strong evidence for the existence of supermassive black hole pairs as well as crucial insight into galaxy mergers in the early Universe.
Astronomers have detected X-rays from Uranus for the first time, using NASA's Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.
Billions of years ago, the Red Planet was far more blue; according to evidence still found on the surface, abundant water flowed across Mars and forming pools, lakes, and deep oceans. The question, then, is where did all that water go?
A new study that characterizes the climate of Mars over the planet’s lifetime reveals that in its earliest history it was periodically warmed, yet remained relatively cold in the intervening periods, thus providing opportunities and challenges for any microbial life form that may have been emerging.
Hubble astronomers are investigating the dimming of one of the most colossal stars ever seen, VY Canis Majoris. Big enough to swallow our solar system out to Saturn’s orbit, the faded star is expelling huge dust clouds late in its life.
Hubble snapped this image of the young comet-like object P/2019 LD2 as it orbits near Jupiter’s captured ancient asteroids, which are called Trojans. The icy object is the first comet astronomers have spotted near the Trojan population.
The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3D atlas of widely separated binary stars within about 3,000 light years of Earth -- 1.3 million of them.
Hubble astronomers have retraced the expanding gaseous debris from a nearby exploded star to estimate the location and time of the stellar detonation. Their analysis reveals that the light from the supernova blast reached Earth about 1,700 years ago.
The most distant quasar known has been discovered. The quasar, observed just 670 million years after the Big Bang, is 1000 times more luminous than the Milky Way. It is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the Sun. Seen more than 13 billion years ago, this fully formed distant quasar is also the earliest yet discovered, providing astronomers with insight into the formation of massive galaxies in the early Universe. The result was released today at the January 2021 meeting of the American Astronomical Society.
In 1995, the Hubble Space Telescope stared at a blank patch of the sky for 10 straight days. The resulting Deep Field image captured thousands of previously unseen, distant galaxies. The Roman Space Telescope will be able to photograph an area of sky 100 times larger than Hubble with the same exquisite sharpness. As a result, a Roman Ultra Deep Field would collect millions of galaxies, including hundreds that date back to just a few hundred million years after the big bang.
A combination of astrophysical measurements has allowed researchers to put new constraints on the radius of a typical neutron star and provide a novel calculation of the Hubble constant that indicates the rate at which the universe is expanding.
Are we alone in the universe? Research by Dr. Gary Zank at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, and collaborators from UAH and other institutions has helped to inform the search for planets that could harbor life.
Data from the Kepler space telescope, launched more than a decade ago, is still helping astronomers who study planets outside of our own solar system — exoplanets — and unravel the mysteries of planetary systems. Initially, astronomers were surprised that Kepler found so many exoplanets, including hundreds of planetary systems with multiple planets orbiting close to their host star. As astronomers developed models to explain the abundance of inner exoplanets, they encountered a new mystery: “Why did Kepler detect just one planet around so many stars, instead of planetary systems with multiple planets?"
Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. But don't worry, this doesn't mean that our planet is plunging towards the black hole.
On November 18 scientists from the US National Science Foundation’s National Solar Observatory predicted the arrival of a large sunspot just in time for Thanksgiving. Using a special technique called helioseismology, the team has been “listening” to changing sound waves from the Sun’s interior which beckon the arrival of a large sunspot.
