Devouring

After recovering from a near-death experience during the most recent crypto winter, Bitcoin miners are back in survival mode — spending billions of dollars on equipment and drawing energy at a record pace ahead of an update in the digital currency's code that threatens revenue streams.  The surge in activity is sparked by a runup in the world's largest cryptocurrency, fueled by newly launched spot Bitcoin exchange-traded funds, and a quadrennial event called the halving that is slated to take place in April. Bitcoin has…

CAPE CANAVERAL, Fla. — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy. While the quasar resembles a mere dot in images, scientists envision a…

Illustration of a tidal disruption event (TDE). A new study by MIT researchers using infrared data has uncovered 18 tidal disruption events in diverse galaxies, expanding our understanding of these phenomena and resolving longstanding puzzles in the field.

Scientists from Cranfield University in the UK are developing a kind of underwater wing for ships that could help decarbonise a sector responsible for more emissions than air travel. Known as wave devouring propulsion technology, it is essentially a flapping foil system installed at the bottom of a ship’s hull that helps propel it along. Inspired by the tail fin of a whale, the system harnesses the kinetic energy of the waves to achieve propulsion without fuel.   As the wing flows through the…

This animation depicts a star experiencing spaghettification as it’s sucked in by a supermassive black hole during a ‘tidal disruption event’. MIT astronomers have discovered the closest tidal disruption event to date using infrared data, revealing a previously hidden population of TDEs in active, star-forming galaxies. Credit: ESO/M. KornmesserThe event was spotted in infrared data — also a first — suggesting further searches in this band could turn up more such bursts.<span class="glossaryLink"…

This artist’s concept shows a planet gradually spiraling into its host star. The Jupiter-size planet pulls gas away from the star, sending it into space. There, the gas cools and becomes dust, which is visible to astronomers. Credit: R. Hurt & K.

This artist’s impression shows a doomed planet skimming the surface of its star. Astronomers used a combination of telescopes to spot the first direct evidence of an aging, bloated sun-like star, like the one pictured here, engulfing its planet. These telescopes included the Zwicky Transient Facility (ZTF) at Caltech’s Palomar Observatory, the W.M. Keck Observatory, and NASA’s NEOWISE mission. Credit: Image: K. Miller/R.

Astronomers using the Gemini South telescope in Chile, operated by NSF’s NOIRLab, have observed the first compelling evidence of a dying Sun-like star engulfing an exoplanet. The “smoking gun” of this event was seen in a long and low-energy outburst from the star — the telltale signature of a planet skimming along a star’s surface. This never-before-seen process may herald the ultimate fate of Earth when our own Sun nears the end of its life in about five billion years. Credit: International Gemini…
