In the World of Astrophysics, One Failed Cancel Campaign Led to Another

The December 19th print edition of the New York Times featured a front-page article by Michael Powell under the title (altered slightly for online purposes), Telescope's Name Ignites Fight on Homophobia .

The story begins with a group of scientists who oppose NASA's decision to name its new deep-space telescope after the agency's 1960s-era leader, James E. Webb (1906–1992).

How the Vera Rubin Telescope Might Find Hidden Planets and Alien Spacecraft

That's why scientists are so excited by the next big thing in giant telescopes. The Vera Rubin Observatory, perched atop an 8,900-foot mountain peak in northern Chile, is on track for completion in late 2023. The U.S.

The Rubin Observatory's 28-foot-diameter telescope and 3.2-gigapixel camera see a huge swathe of the sky in the optical spectrum. Basically, the same part of the spectrum we see with our own eyes.

Webb Space Telescope Makes Stunning Discovery: Unveils Previously Shrouded Newborn Stars

By Rice University December 25, 2022 Astronomers from Rice University and other organizations dug deep into the data from this near-infrared image, one of the first taken by NASA's James Webb Space Telescope.

Rice University astronomer Megan Reiter and colleagues took a "deep dive" into one of the first images from NASA's James Webb Space Telescope and were rewarded with the discovery of telltale signs from two dozen previously unseen young stars about 7,500 light years from Earth.

Space satellites could give us clean energy — if they overcome a key obstacle

At first glance, remote mines would be an excellent candidate to be powered by a solar-power satellite. Many aren't anywhere near a power grid connection, and it would be too costly to run electric lines directly there.

But, as with so much technology, it comes down to cost. On average, a typical mine pays $.30 per kWh of operation, so in a best-case scenario, that is the price that a power satellite would have to be at least close to.

The mystery of Space Hurricanes: STRANGE solar storm happens nowhere else | Tech News

While the name 'space hurricane' sounds like the name of a badly made science fiction movie, it is real and is one of the strangest space weather phenomena scientists have come across. In fact, it is not even fully solved yet.

A study was published in the Nature journal last year titled 'A space hurricane over the Earth's polar ionosphere'. The researchers claimed to have discovered cyclone-like auroras near the North Pole.

New study models the transmission of foreshock waves towards Earth -- ScienceDaily

An international team of scientists led by Lucile Turc, an Academy Research Fellow at the University of Helsinki and supported by the International Space Science Institute in Bern has studied the propagation of electromagnetic waves in near-Earth space for three years.

"How the waves would survive passing through the shock has remained a mystery since the waves were first discovered in the 1970s. No evidence of those waves has ever been found on the other side of the shock," says Turc.

China's space station releases small test satellite into orbit | Space

China has released a small test satellite into orbit from its recently completed Tiangong space station.

The satellite was released from a deployer on the Tianzhou 5 cargo ship, which is currently docked at Tiangong . Tianzhou 5 launched on Nov.

The 26.5-pound (12 kilograms) satellite designated XW-4 (CAS-10) was released at 9:30 p.m. EST on Dec. 17 (0130 GMT on Dec. 18). The small spacecraft, also known as the Macao Student Science Satellite 1, carries both optical camera and radio payloads.

Behold! This gorgeous galaxy image merges Hubble and Webb data in stunning detail

The Hubble and Webb Space Telescopes join forces to give us this dazzling and colorful view of spiral galaxy NGC 1566: a swirling scaffolding of dense dusty filaments, shining star clusters, and bright bursts of star formation, with a supermassive black hole at its blazing heart.

Auroras might be visible from northern Maine or Michigan tonight | Space

The National Oceanic and Atmospheric Administration (NOAA) forecasts a minor, G1-scale storm from the sun tonight (Dec. 23) that could generate northern lights once the solar particles hit the atmosphere of Earth and interact with our planet's magnetic field lines.

While that sounds exciting, it will be likely very difficult for U.S. observers to see any potential northern lights as a "bomb cyclone" is driving a massive winter storm across the northern and eastern United States.
