An overview of world astronomy developments in the past year

Last year was a good year for astronomy, and the images sent by the James Webb Space Telescope opened the human eye to the greatness of the universe.

Next, we review the most important astronomical news of the year:

James Webb Space Telescope

Undoubtedly, the biggest and best news of 2022 was the deployment of the James Webb Space Telescope and the flood of images that followed. Since then, Jamesob has continued to provide amazing views of newborn stars, dying stellar giants, rotating galaxies, and worlds very close to us. Views that depict the greatness of the universe.

Artemis launch 1

After months of delay, the first test flight of the space launch system and the Orion capsule took place. Artemis 1 successfully launched and sent back stunning views of Earth and the Moon before crashing back into the Pacific Ocean. On its way, this satellite placed 10 cubesats (a type of small satellites) in different orbits.

A collision with an asteroid

NASA’s Double Asteroid Redirection Test (DART) mission successfully hit Dimorphos (a small asteroid’s moon). Not only was the collision a success, but so was the change in direction, as ground- and space-based telescopes recorded a significant (32-minute) change in the asteroid’s orbit. Astronomers are still analyzing stunning images of this targeted impact and its debris to fully understand its impact on the asteroid system.

A call for a mission to Uranus

The planetary science community has released its prioritized wish list for the next 10+ years, a document that will help guide NASA mission decisions. At the top of the list is the mission to the ice giant Uranus

Low Earth orbit satellites are getting brighter

Satellites are being launched into low Earth orbit at an increasing speed, resulting in a more crowded sky. Astronomers, meanwhile, have a bigger worry because the aerospace company AST Space Mobile has launched a satellite called Blue Walker 3, which is now brighter than many stars between magnitude 4 and 0. This satellite is the prototype of the Blue Bird satellite constellation. Its members will have even larger panels and therefore will be even brighter than the Blue Walker 3.
