We know that there are thousands of exoplanets out there, with many millions more waiting to be discovered. But the vast majority of exoplanets are simply uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.

Sourabh Shubham: “This area of Mars is known to have a wide variety of hydrated minerals spanning a long stretch of Martian history. A volcanic setting for these minerals had long been suspected. So, it may not be too surprising to find a volcano here. In some sense, this large volcano is a long-sought ‘smoking gun’.”

The planet Mars is known for its vast array of inactive shield volcanoes, and a new volcano could be added to the family with a recent study presented at the 55th Lunar and Planetary Science Conference, as a team of researchers announced the discovery of a massive volcano on Mars that is buried underneath the surface and could even possess a base comprised of glacier ice. This study holds the potential to help scientists better understand past volcanism and glaciation on the Red Planet that could provide clues to Mars’ geologic history.

For the study, the researchers used images from the High Resolution Imaging Science Experiment (HiRISE) camera and data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), which are both onboard NASA’s Mars Reconnaissance Orbiter (MRO), along with data from the Mars Orbiter Laser Altimeter (MOLA) that was onboard the Mars Global Surveyor to analyze “Noctis Mons” (official name pending), which is located southeast of Mars’ Tharsis volcanic region and in the western region of Valles Marineris, known as the largest and deepest canyon in the solar system.

There are so many investments that we could be making, but there are also Moonshots.

Research utilizing the James Webb Space Telescope highlights the destructive power of ultraviolet “winds” on the gas in protoplanetary disks surrounding young stars, shedding light on the intricate dynamics that limit the formation of gas giants in the cosmos.

Ultraviolet “winds” from nearby massive stars are stripping the gas from a young star’s protoplanetary disk, causing it to rapidly lose mass, according to a new study. It reports the first directly observed evidence of far-ultraviolet (FUV)-driven photoevaporation of a protoplanetary disk. The findings, which use observations from the James Web Space Telescope (JWST), provide new insights into the constraints of gas giant planet formation, including in our own Solar System.

Now, astronauts who witness solar eclipses do so from the International Space Station (ISS). But instead of looking at the sun, they look down at the Earth to observe a solar eclipse. “ISS astronauts can see the [moon’s] shadow but not the eclipse itself, because their windows don’t point toward the sun,” says Levasseur. Rather, remotely operated equipment on the station collects data from the eclipse, while astronauts peer at the darkened ground on the planet below.

The first time anyone got this unique view was in 1999, when Russian cosmonauts Viktor Afanasyev and Sergei Avdeyev, as well as French astronaut Jean-Pierre Haigneré, witnessed the 20th century’s final total solar eclipse from the former Russian space station, Mir. On August 11, they saw the moon’s shadow pass over England.
