Rocks and minerals contribute essential raw materials for any civilization, and in a technological society minerals (and the rare elements they contain) are especially sought after. In the past, most discoveries of mineral deposits have resulted from perseverance and luck.

In the last 200 years scientists realized that minerals are not distributed randomly. Many of the over 5,000 different minerals occurring on Earth exist in a so-called paragenesis. A paragenesis is a mineral assemblage formed under specific physico-chemical rules, like a certain chemical composition of the host rock or when the right conditions — like temperature and pressure — are met.

A machine learning model can predict the locations of minerals on Earth — and potentially other planets — by taking advantage of patterns in mineral associations.

NASA is offering everyone the opportunity to have their name sent on the 1.8-billion-mile journey to Jupiter next year.

The “Message in a Bottle” campaign (Opens in a new window) invites people to submit their names to NASA before 11:59 pm EST on Dec. 31, 2023. Those names will then be engraved on a microchip alongside a poem titled “In Praise of Mystery: A Poem for Europa” written by U.S. Poet Laureate Ada Limón.

Once completed, the chip will be loaded on to NASA’s Europa Clipper spacecraft (Opens in a new window) scheduled for launch in October 2024. It won’t reach Jupiter until April 2030, at which point Clipper will orbit the planet and make close to 50 flybys of the Europa moon at altitudes as low as 16 miles (25 kilometers) above the surface. The aim is to investigate whether Europa has the potential to support life.

The idea of solar energy being transmitted from space is not a new one. In 1968, a NASA engineer named Peter Glaser produced the first concept design for a solar-powered satellite. But only now, 55 years later, does it appear scientists have actually carried out a successful experiment. A team of researchers from Caltech announced on Thursday that their space-borne prototype, called the Space Solar Power Demonstrator (SSPD-1), had collected sunlight, converted it into electricity and beamed it to microwave receivers installed on a rooftop on Caltech’s Pasadena campus. The experiment also proves that the setup, which launched on January 3, is capable of surviving the trip to space, along with the harsh environment of space itself.

“To the best of our knowledge, no one has ever demonstrated wireless energy transfer in space even with expensive rigid structures. We are doing it with flexible lightweight structures and with our own integrated circuits. This is a first,” said Ali Hajimiri, professor of electrical engineering and medical engineering and co-director of Caltech’s Space Solar Power Project (SSPP), in a press release published on Thursday.

Science educator Bill Nye joins CNN’s Jim Acosta to explain the significance of the detection of phosphorus in salty ice grains on Saturn’s moon Enceladus.

NASA’s Aqua satellite spotted giant ice swirls stretching for hundreds of miles in the Sea of Okhotsk off Russia’s P’yagina Peninsula.

They believe the process could take roughly a quadrillion years.

A team of astronomers discovered a star that is gradually crystallizing into an enormous diamond. Scientists believe it is at the beginning of a process that takes roughly a quadrillion years, a report from Space.com reveals. As the universe is 13.6 billion years old, no star has ever fully crystallized.

The discovery sheds new light on the evolution of stars as they gradually transform over time.

Once in the hands of NASA scientists, the photos were turned into panoramic images. Color was also added to the photos, creating what NASA referred to as a “postcard,” and further emphasizing the difference between the two times the photos were taken.

The panoramic postcard shows a number of Mars landmarks, including “Marker Band Valley,” where Curiosity once found evidence that there may have been a lake on the site, and two hills named “Bolivar” and “Deepdale.” At the edge of the photo is the rim of the Gale Crater, which Curiosity is currently exploring. Because the photograph was taken on a clear day, Curiosity’s image even shows a mountain that is 54 miles from the edge of the crater.

Galaxies dating back to the Epoch of Reionization show abundant signs of young stars.
