Scientists discover drier mantle on moon’s farside, offering potential insight on lunar evolution

Chinese scientists have discovered that the moon’s mantle contains less water on the lunar farside than on the nearside, based on analysis of basalts collected by the Chang’e-6 (CE6) lunar mission.

Where to find the next Earth: Machine learning accelerates the search for habitable planets

A team from the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has developed a machine-learning model that predicts potential planetary systems with Earth-like planets. The model could significantly accelerate and thus revolutionize the future search for habitable planets in the universe.

Hubble studies a nearby galaxy’s star formation

This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941, which lies about 67 million light-years from Earth in the constellation Virgo (The Maiden). Because this galaxy is nearby, cosmically speaking, Hubble’s keen instruments are able to pick out exquisite details such as individual star clusters and filamentary clouds of gas and […]

JWST observations detect dusty disk around the central star of Ring Nebula

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated Messier 57 (also known as NGC 6720), dubbed the Ring Nebula. As a result, they found that the central star of this nebula is surrounded by a dusty ring. The finding was detailed in a paper published […]

A year after the solar eclipse, Dallas area scientists are still uncovering cosmic clues

For some Dallas-area scientists, the total solar eclipse on April 8, 2024, was more than just a once-in-a-lifetime cosmic spectacle: It was a rare and invaluable research opportunity, the perfect controlled experiment.

Researcher proposes first-time model that replaces dark energy and dark matter in explaining nature of the universe

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a paper in the journal Classical and Quantum Gravity that proposes a universe built on steps of multiple singularities rather than the Big Bang alone to account for the expansion of […]

Do ‘completely dark’ dark matter halos exist?

Every galaxy is thought to form at the center of a dark matter halo—a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don’t yet know whether star-free dark matter halos exist.

Observations explore the persistent nature of X-ray binary 4U 0728-25

Using ESA’s XMM-Newton satellite, Italian astronomers have observed a Galactic X-ray binary system known as 4U 0728-25. Results of the new observations, presented in a research paper published March 28 on the arXiv preprint server, shed more light on the persistent nature of this source.

Saturn’s moon Titan could harbor life, but only a tiny amount, study finds

Titan, Saturn’s largest moon, is a strange, alien world. Covered in rivers and lakes of liquid methane, icy boulders and dunes of soot-like “sand,” its topography has long fascinated scientists and invited speculation on whether life-forms might lurk beneath the moon’s thick, hazy atmosphere.

NASA and ESA want to bring Martian rocks to Earth. Here’s what will happen to the samples once they get here

A mission will deliver rock and soil from Mars to laboratories on Earth in the 2030s. Mars Sample Return (MSR) is led by NASA with participation from the European Space Agency (ESA). The mission will allow scientists to use the best laboratory instruments on Earth to determine whether Mars hosted microbial life billions of years […]
