Located in the Okanagan Valley outside of Penticton, British Columbia, there is a massive radio observatory dedicated to observing cosmic radio phenomena. It’s called the Canadian Hydrogen Intensity Mapping Experiment (CHIME), a cylindrical parabolic radio telescope that looks like what snowboarders would call a “half-pipe.” This array is part of the Dominion Radio Astrophysical Observatory (DRAO), overseen by the National Research Council (NRC).

With its small satellite launch business booming, SpaceX is set to double its cadence of dedicated rideshare missions this year, beginning with the liftoff of a Falcon 9 rocket Thursday from Cape Canaveral with 105 spacecraft for customers in 20 countries.
Astronomy Jargon 101: Ionosphere
In the upper reaches of the Earth’s atmosphere, the intense UV and X-ray radiation from the Sun bombards molecules and atoms, causing them to split apart. The resulting positively charged nuclei are called ions, and the free electrons are called…free electrons. These charged particles behave differently than normal neutral molecules, especially when it comes to how they interact with radio waves.
NASA getting SLS megarockets ready for crewed moon missions
The first SLS mission, an uncrewed flight around the moon, is scheduled to launch in March. Crewed missions are slated to follow in 2024 and 2025.

China’s Lander Has Detected Water on the Moon
China’s Chang’e-5 lunar lander has found evidence of hydroxyl (OH) on the Moon. Hydroxyl is a close chemical cousin of water, H2O. While several other orbital missions have detected OH on the Moon previously, Chang’e-5 marks the first time it has been detected by a spacecraft sitting on the lunar surface.

Giant galactic bubble is driving star formation, new study finds
Earth is surrounded by a vast bubble about 1,000 light-years wide whose borders drive the formation of all nearby young stars, a new study finds.
The Milky Way’s Most Recent Meal was a Galaxy it Gobbled up 8-10 Billion Years ago
A central aspect of galactic evolution is that they must eat or be eaten. Dark energy strives to push galaxies apart, but gravity tries to pull them together. As a result, galaxies tend to form into local groups. As these superclusters of galaxies become more isolated due to cosmic expansion, they gravitationally turn on each other, and in time the largest galaxies of the group will consume the smaller ones. The Milky Way is one of the larger galaxies in our local group, and so it has consumed smaller galaxies in the past. But piecing together the history of these galactic meals is a real challenge.
Stellar Streams Are Revealing Their Secrets

Astronomy Jargon 101: Kirkwood Gaps
In 1866 the American astronomer Daniel Kirkwood was studying all the known asteroids, which at the time amounted to several hundred. If you just look at a snapshot of the solar system, there’s nothing that particularly stands out about the asteroids. They appear to have all sorts of random positions and random orbits within the main asteroid belt, which sits halfway between Mars and Jupiter.
