Quantum computing: Cold chips can control qubits

Researchers and engineers from QuTech in the Netherlands and from Intel Corp., jointly designed and tested a chip to control qubits that can operate at extremely low temperatures, and opens the door to solving the "wiring bottleneck," an important step toward a scalable quantum computer. Their results are published in the scientific journal Nature.

There's been a breakthrough in the case of the missing planets.

Supermassive black holes devour gas just like their petite counterparts

On Sept. 9, 2018, astronomers spotted a flash from a galaxy 860 million light years away. The source was a supermassive black hole about 50 million times the mass of the sun. Normally quiet, the gravitational giant suddenly awoke to devour a passing star in a rare instance known as a tidal disruption event. As the stellar debris fell toward the black hole, it released an enormous amount of energy in the form of light.

Rocket Lab's satellite launch from New Zealand site fails

California-based Rocket Lab said a launch of satellites from its facility in New Zealand failed Saturday.

60 years later, is it time to update the Drake equation?

On November 1, 1961, a number of prominent scientists converged on the National Radio Astronomy Observatory in Green Bank, West Virginia, for a three-day conference. A year earlier, this facility had been the site of the first modern SETI experiment (Project Ozma), where famed astronomers Frank Drake and Carl Sagan used the Green Bank telescope (aka "Big Ear") to monitor two nearby sun-like stars—Epsilon Eridani and Tau Ceti.

Scientists hunt for evidence of 'lensed' gravitational waves

Scientists searching for evidence of lensed gravitational waves have published new research outlining the most recent findings on their quest for the first detection of these elusive signals.

Dark Energy Spectroscopic Instrument (DESI) starts 5-year survey

A five-year quest to map the universe and unravel the mysteries of "dark energy" is beginning officially today, May 17, at Kitt Peak National Observatory near Tucson, Arizona. To complete its quest, the Dark Energy Spectroscopic Instrument (DESI) will capture and study the light from tens of millions of galaxies and other distant objects in the universe.

Space law protects you from falling debris, but there are no legal penalties for leaving junk in orbit

On May 8, 2021, a piece of space junk from a Chinese rocket fell uncontrolled back to Earth and landed in the Indian Ocean near the Maldives. A year ago, in May 2020, another Chinese rocket met the same fate when it plummeted out of control into the waters off the West African coast. No one knew when or where either of these pieces of space junk were going to hit, so it was a relief when neither crashed on land or injured anyone.

Solar Orbiter images first coronal mass ejections

The Solar Orbiter launched on 10 February 2020 and is currently in cruise phase ahead of the main science mission, which begins November this year. While the four in situ instruments have been on for much of the time since launch, collecting science data on the space environment in the vicinity of the spacecraft, the operation of the six remote sensing instruments during cruise phase is focused primarily on instrument calibration, and they are only active during dedicated checkout windows and specific campaigns.

Technology news

Researchers create new zinc-air pouch cells

Zinc-air batteries (ZABs) are among the most promising next-generation battery technologies due to their many advantageous characteristics. Most notably, these batteries have unique half-open structures, a significant theoretical energy density (1,086 and 1,370 Wh kg−1 when including and excluding oxygen, respectively), flexible electrodes and an inherently aqueous electrolyte. Moreover, in contrast with other materials used in batteries, Zinc (Zn) is less harmful for the environment and more abundant.

Study tests viability of Tesla's 100-year old patented device

A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
