A recent study presented at the National Astronomy Meeting 2023 (NAM2023) examines a newly discovered planetary formation theory that challenges previous notions on how planets are formed in the disks of gas and dust surrounding young stars, also known as protoplanetary disks. Along with being presented at NAM2023, the study has also been submitted for peer-review to the journal Monthly Notices of the Royal Astronomical Society and holds the potential to help scientists better understand not only how planets form, but how life could form on them, as well.

A recent study published in Nature examines a volcanic hotspot that potentially exists beneath a feature on the Moon’s farside (the side facing away from the Earth) called the Compton-Belkovich Thorium Anomaly. Researchers led by the Planetary Science Institute collected data from the hotspot region using microwave instruments onboard the China National Space Administration’s Chang’e-1 and Chang’e-2 orbiters and holds the potential to help scientists better understand the past volcanic processes on our nearest celestial neighbor, as surface evidence indicates lunar volcanic activity ceased between 3 to 4 billion years ago.

An independently appointed review board recently announced that NASA, their Jet Propulsion Laboratory (JPL), and the California Institute of Technology (Caltech) have exceeded expectations in taking steps to ensure the successful launch of the metal-rich-asteroid-hunting Psyche mission this October. This comes after Psyche’s initial launch date was delayed from August 2022 due to late delivery of the spacecraft’s flight software and testing equipment, which prevented engineers from performing the necessary checkouts prior to launch.

A recent study published in Science examines how thin channels inside impact craters on Mars could have formed from Martian gullies, which share similar characteristics with gullies on Earth and are typically formed from cascading meltwater, despite the Martian atmosphere being incapable of supporting liquid water on its surface. However, the researchers hypothesize these gullies could have formed during periods of high obliquity, also known as axial tilt, on Mars, which could have resulted in a brief rise in surface temperatures that could have melted some surface and subsurface ice, leading to meltwater cascading down the sides of impact craters across the planet.

NASA recently used its powerful High Resolution Imaging Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter to take a breathtaking image of a dust devil traversing Syria Planum on Mars. One unique aspect of dust devils is their shadows can be used to estimate their height, which have been estimated to reach 20 km (12 miles) into the Martian sky. Studying dust devils on Mars is a regular occurrence for the scientific community and can help scientists better understand surface processes on other planets. But with the atmospheric pressure on Mars being only a fraction of Earth’s, what processes are responsible for producing dust devils?

In a recent study published in The Astrophysical Journal Letters, a team of astronomers used the W. M. Keck Observatory on Maunakea, Hawai?i Island to identify exoplanet, AF Lep b, which is three times the mass of Jupiter orbiting a Sun-sized star located approximately 87.5 light-years from Earth. What makes this discovery unique is AF Lep b is the first exoplanet discovered using a method called astrometry, which involves measuring unexpected, miniscule changes in the position of a star relative to nearby stars, which could indicate another object, an exoplanet, is causing gravitational tugs on its parent star.

Engineers at NASA’s Jet Propulsion Laboratory (NASA-JPL) are busy keeping the Perseverance rover and Ingenuity helicopter functioning in Jezero Crater on Mars while these robotic explorers continue the search for ancient microbial life on the Red Planet. But some of those same engineers have also been busy working with LEGO designers on new one-tenth-scale LEGO Technic buildable models of these very same robotic explorers with the goal of inspiring the next generation of NASA scientists and engineers.

A professor from Northumbria University in the North East region of England has been granted telescope time with NASA’s James Webb Space Telescope (JWST) later this year to study Jupiter’s upper atmosphere, also known as its ionosphere. Being granted such access to JWST is extremely competitive which makes getting access to use its powerful instruments to study the cosmos a very high honor.

NASA recently welcomed the newest signatories of the Artemis Accords as Spain, Ecuador, and India became the 25th, 26th, and 27th countries, respectively, to sign on to the historic agreement for cooperation and partnership for space exploration, specifically pertaining to NASA’s Artemis program.

A recent study published in Astrobiology examines the likelihood of the planet Venus being able to support life within the thick cloud layer that envelopes it. This study holds the potential to help us better understand how life could exist under the intense Venusian conditions, as discussions within the scientific community about whether life exists on the second planet from the Sun continue to burn hotter than Venus itself.
