A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published June 16 in Science.
Astronomers using a fleet of world leading telescopes on the ground and in space have captured images of a periodic rocky near-Sun comet breaking apart.
A new study shows a deep connection between some of the largest, most energetic events in the universe and much smaller, weaker ones powered by our own Sun.
In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres.
New chemistry ‘forensics’ indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion.
For the past thirty years, the star β Pictoris has fascinated astronomers because it enables them to observe a planetary system in the process of formation.
If not for the soupy, fast-moving atmosphere on Venus, Earth’s sister planet would likely not rotate.
The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.
The innermost lane may typically be favored to win a race, but in Jupiter’s Great Red Spot, the winds in its outermost “lane” are taking the lead! Only Hubble can spot these trends: The observatory acts like a storm tracker for the giant planets in our solar system every year.
Using the powerful 570-megapixel Dark Energy Camera (DECam) in Chile, astronomers just ten days ago discovered an asteroid with the shortest orbital period of any known asteroid in the Solar System.
Within meteorites, the magnetic fields associated with the particles that make up the object can act as a historical record.
For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact.
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.
New Brunswick, N.J. (Feb. 22, 2021) – Rutgers University–New Brunswick Professor Kristen McQuinn is available for interviews on the upcoming launch of the James Webb Space Telescope, its potential scientific impact and the leap forward it will provide in our understanding of the…
A giant dark storm on Neptune heading for certain doom at the equator mysteriously halted its journey and began drifting in the opposite direction. Almost simultaneously, another smaller dark spot appeared nearby, only to vanish months later. Hubble astronomers are presenting these findings today at the Fall 2020 American Geophysical Union meeting.
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
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?”
The star HL Tauri, 450 light-years from Earth, is glowing at the center of a system of concentric rings made from gas and dust and producing planets, one for each gap in the ring. Its discovery has shaken solar system origin theories to their core. Mayer Humi, a scientist from the Worcester Polytechnic Institute, believes it provides an apt study target for theories about protoplanetary rings around stars. The research is published in the Journal of Mathematical Physics.
Astronomers used Hubble during a total lunar eclipse to detect ozone in our planet’s atmosphere by looking at Earthlight reflected off the Moon in ultraviolet wavelengths. This method serves as a proxy for how astronomers will observe Earth-like exoplanets in search of life.
X-ray experiments at Berkeley Lab played a key role in resolving the origin of rare, odd meteorites that have puzzled scientists since their discovery a half-century ago. Known as type IIE iron meteorites, they appear to have originated from a parent body that had a composition featuring both fully melted and unmelted parts – other meteorite types display only one composition.
Hubble photographed Saturn and its rings on July 4, during summer in Saturn’s northern hemisphere. This image is taken as part of the Outer Planets Atmospheres Legacy (OPAL) project. OPAL is helping scientists understand the atmospheric dynamics and evolution of our solar system’s gas giant planets.
After examining a dozen types of suns and a roster of planet surfaces, Cornell University astronomers have developed a practical model – an environmental color “decoder” – to tease out climate clues for potentially habitable exoplanets in galaxies far away.
Two Weizmann Institute scientists are on a team selected as a finalist for a mission to Triton, Neptune’s largest moon. The duo designed a super-accurate clock that will help them study Triton’s atmosphere – and even search for life. The mission, called Trident, would launch in 2026.
When the sun expels plasma, the solar wind cools as it expands through space — but not as much as the laws of physics would predict. UW–Madison physicists now know the reason.
Scientists will use NASA’s James Webb Space Telescope study three mysterious, cold, dense clouds where high-mass stars form.
Lawrence Livermore National Laboratory (LLNL) scientists and a collaborator from the University of Münster reviewed recent work that shows how meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC – rocks or sediments containing carbon or its compounds) groups, which most likely represent material from the inner and outer solar system.
Hubble captured interstellar comet 2I/Borisov streaking past the Sun in a pair of images taken on November 16 and December 9. It is the first confirmed interstellar comet known to have passed through the solar system.
The shrinking of the clouds of the Great Red Spot on Jupiter has been well documented with photographic evidence from the last decade. However, researchers said there is no evidence the vortex itself has changed in size or intensity.
Hubble has taken the sharpest view to date of interstellar comet 2I/Borisov whose speed and trajectory indicate it has come from beyond our solar system. The image, taken October 12, 2019, reveals a central concentration of dust around the comet’s nucleus.
MOSCOW (MIPT) — The discovery by Michel Mayor and Didier Queloz was momentous in that they made it very clear how exoplanets may be sought using what is known as the radial velocity method, says Alexander Rodin from the Moscow Institute…
This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet’s trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter’s turbulent atmosphere than seen in previous years.

The summer solstice is the longest day of the year and occurs when one of Earth’s poles has its maximum tilt toward the sun, and the sun reaches its highest position in the sky. In the U.S., the summer solstice…
