During the first 500 million years of cosmic history, the first stars and galaxies formed, seeding the Universe with heavy elements and eventually reionizing the intergalactic medium.

A “living asteroid” – or sea star – is lurking off the coast of southern Australia, in waters 3,850 metres deep.

It’s the deepest known occurrence of a sea star in the continent’s waters, and also a brand-new species.

The sea star, dubbed Poraniomorpha tartarus, was collected in a 2017 ocean expedition led by the Museums Victoria Research Institute.

Further boosting this ethos of accessibility is the fact that Hestia will be compatible with both iOS and Android phones. Dupuy pointed out that even a smartphone that is around five years old will work with Hestia for taking images of the sun and the moon, but to see more deep field objects like nebulas, a more recent and more sensitive smartphone such as an iPhone 12 or 13 may be required.

Vaonis, launched in 2016, is no stranger to introducing astronomy equipment via a Kickstarter campaign. In 2020 they successfully launched the Vespera smart telescope after a fund-raising program. The difference between Hestia and previous projects is this smartphone telescope project is much more affordable.

“It was possible to better in terms of price,” Dupuy said. “We wanted to use all the image processing experience we have gained to develop an app and to create a very affordable new product.”

For a metal meteorite to retain a magnetic field, its parent asteroid may need a cold rubble core to help drive an internal dynamo.

A century-old mystery of how galaxies change shapes has been solved by considering “survival of the fittest” collisions between cosmic titans.

TAMPA, Fla. — Intelsat said Aug. 14 it is due for a $3.7 billion windfall late this year after becoming the latest satellite operator to clear C-band spectrum ahead of schedule for terrestrial 5G telcos in the United States.

Weeks after launching its seventh and final C-band clearing satellite, the company said it had achieved certification for work to move broadcast customers into a narrower swath of the spectrum.

The Federal Communications Commission set a deadline for satellite operators to clear the spectrum by December 2025, but offered them nearly $10 billion in incentive payments if they could make the frequencies available for telcos before Dec. 5, 2023.

Last year, NASA undertook its first planetary defense mission with the Double Asteroid Redirection Test (DART). The goal was to divert the moonlet Dimorphos from its orbit, demonstrating that an asteroid could be redirected in the case of a catastrophic course toward Earth.

The spacecraft’s impact, while altering the moonlet’s orbit, also resulted in the dispersal of 37 boulders from its surface. Some of these space rocks are as wide as 22 feet off its surface.

The DART mission was watched intently across the globe on September 26, 2022. The spacecraft successfully shifted Dimorphos’s orbit from an original 11 hours and 55 minutes to 11 hours and 23 minutes post-impact.

Scientists have discovered fossil evidence of a cyclical climate on Mars, with wet and dry seasons like those on Earth. This environment, in which simple organic molecules have already been discovered, may have provided ideal conditions for the formation of complex organic compounds.
