On 17 January, the Artemis II Space Launch System rocket and Orion spacecraft were rolled out from the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, to Launch Pad 39B. The 6.5-km journey took around 12 hours and was carried out using NASA's crawler-transporter, which has been moving rockets to launch pads for over 50 years.

The U.S. Space Force is set to send its ninth third-generation Global Positioning System (GPS) satellite into medium Earth orbit on Monday night. The satellite will ride to space on a SpaceX Falcon 9 rocket after the government moved the spacecraft from a United Launch Alliance Vulcan rocket.
Supermassive Black Holes (SMBHs), which reside at the center of many galaxies, play a central role in the evolution of these cosmic structures. This includes how they power Active Galactic Nuclei (AGNs), in which the core region emits enough radiation and light to temporarily outshine all the stars in the disk. They also "seesaw" between relativistic jets emanating from their poles to outflows of jets that suppress star formation in the surrounding core. Despite this broad understanding, scientists have been waiting for the day when they can peer directly into the heart of a galaxy's core and see what's going on there.

We frequently question whether we are alone in the universe.
The Wolf Moon is named for the hungry predators that sometimes can be heard howling in the winter month.
Earthquake sensors can detect sonic booms generated by reentering space debris to help track the potentially dangerous objects in near real time.
We live near a fusion reactor in space that provides all our heat and light. That reactor is also responsible for the creation of various elements heavier than hydrogen, and that's true of all stars. So, how do we know that stars are element generators? Many clues lie hidden in stellar spectra, since they contain fingerprints of various elements cooked up by the stars.
"Stars like the sun don’t just stop shining for no reason."
Artemis 2 is at the launch pad, but several big tests must be performed before it launches as soon as Feb. 6.
Some galaxies in the early universe were absolute powerhouses, churning out stars at rates that would dwarf the Milky Way's modest stellar production. These "monster galaxies," buried deep in dust between 10 and 12 billion years ago, are thought to be the ancestors of today's giant elliptical galaxies. But what drove them to grow so violently has remained frustratingly unclear.
A team of predominantly Canadian researchers are using massive galaxy clusters and the JWST to study low-mass galaxies from 13.5 billion years ago all the way up to 5 billion years ago. The clusters are used as gravitational lenses to expand the JWST's reach. It's called CANUCS, the Canadian NIRISS Unbiased Cluster Survey.
Blue Origin will use a flight-proven booster on the next launch of its New Glenn rocket. The liftoff, which is targeted for late February, will be just the third for New Glenn to date.
