This week’s photo is from the European Space Agency (ESA) and shows a recently-completed telescope in Chile designed to detect dangerous asteroids. Here is the full story:
Part of the world-wide effort to scan and identify near-Earth objects, the European Space Agency’s Test-Bed Telescope 2 (TBT2), a technology demonstrator hosted at ESO’s La Silla Observatory in Chile, has now started operating. Working alongside its northern-hemisphere partner telescope, TBT2 will keep a close eye on the sky for asteroids that could pose a risk to Earth, testing hardware and software for a future telescope network.
This week’s photo is a “lunar transit” of the International Space Station (ISS) taken on January 18, 2022. The details in the photo are impressive, including Tycho crater. The Mashable article accompanying this image states:
The silhouette of the space station is so clear, observers can make out a faint grid pattern on its solar panel arrays. The attached SpaceX Crew-3 spacecraft, which brought up NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, as well as European Space Agency astronaut Matthias Maurer in November, is easily identifiable.

This week’s image from the Hubble Space Telescope shows the Flame Nebula in the constellation Orion, as explained by NASA:
The Flame Nebula, also called NGC 2024, is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. It’s a portion of the Orion Molecular Cloud Complex, which includes such famous nebulae as the Horsehead Nebula and Orion Nebula. This image focuses on the dark, dusty heart of the nebula, where a star cluster resides, mostly hidden from view. Nearby (but not visible in this image) is the bright star Alnitak, the easternmost star in the Belt of Orion. Radiation from Alnitak ionizes the Flame Nebula’s hydrogen gas. As the gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the visible glow behind the swirled wisps of dust.

The image above is from the Hubble Space Telescope and shared on NASA’s site last month under the title “Hubble Spots a Starship-Shaped Galactic Pair.” While the author of the story below seesthe USS Enterprise from Star Trek, I see a decloaking Klingon Bird-of-Prey. Here is the full description from NASA:
The subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The two galaxies in the upper right of the image appear to be interacting with one another — indeed, the long trails of stars and gas extending from them both give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image. In reality, however, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another. It is also unclear whether the galaxy to the lower left is actually interacting with the other two, although they are so relatively close in space that it seems possible that they are. By happy coincidence, the collective interaction between these galaxies have caused the two on the upper right to form a shape, which from our Solar System’s perspective, ressembles the starship known as the USS Enterprise from Star Trek!
NGC 7764A, which lies about 425 million light years from Earth in the constellation Phoenix, is a fascinating example of just how awkward astronomical nomenclature can be. The three galaxies are individually referred to as NGC 7764A1, NGC 7764A2 and NGC 7764A3, and just to be really difficult, an entirely separate galaxy, named NGC 7764, sits in the skies about a Moon’s distance (as seen from Earth) away. This rather haphazard naming makes more sense when we consider that many of the catalogues for keeping track of celestial bodies were compiled well over 100 years ago, long before modern technology made standardising scientific terminology much easier. As it is, many astronomical objects have several different names, or might have names that are so similar to other objects’ names that they cause confusion.

The image above is an artist’s rending of Russia’s Luna-25 Moon Station that was to be launched last year and is now scheduled to be launched in July 2022. It will be the first domestic spacecraft in the country’s modern history on the surface of the Moon. Luna-25 will be equipped with a soil-sampling robotic arm and camera to image the terrain. The last lunar mission was Luna-24 in 1976 by the then Soviet Union, which returned Moon samples to the Earth.
