these objects 
before they come calling through our neck of the woods." https://arstechnica.com/space/2025/02/asteroid-2024-yr4-may-be-a-dud-but-we-will-soon-find-many-more-threats

Which #astronomers and #planetaryscience nerds in the #fedi will be covering the #planetaryalignment this week. Yes, I am very geeked for this moment. 7 out of 9 doesn’t happen often.
Point me to the science.
Enabled by supercomputing, University of Pretoria (UP) researchers have led an international team of #astronomers that has provided deeper insight into the entire life cycle (birth, growth and death) of giant #radio #galaxies, which resemble “cosmic fountains”

Our #astronomy focused episode on #Lynx includes a discussion of the origins of the name of this constellation... and we just have one thing to say...

When discovered in 2004, #Apophis was thought to have a 2.7% chance of colliding with Earth in 
2029. In 2021, #NASA ruled out these collision 
risks after refining its trajectory, but recent simulations have revived some concerns.
#2024YR4 will be too distant for radar observations until 2032, when it could strike Earth. #Astronomers need more data to refine its exact orbit https://www.forbes.com/sites/jamiecartereurope/2025/02/02/a-deadly-asteroid-may-strike-earth-in-2032---what-to-know

How did we get to talking about Fritz Zwicky (who we agreed is 'brat') anyway?
Well, this is I Zwicky 18 -- Jordan's runner up for Gold Star for the #constellation #UrsaMajor -- named after the genius curmudgeon #astronomer.

@VRubinObs Today, #astronomers are aware of only about 40 percent 
of potentially hazardous #asteroids - close-flying objects that are large enough to cause continent-wide destruction if they were to impact Earth. "The idea is, if there is an object like that, we want to find it while it’s maybe 40 or 50 years out, because that gives us enough time to figure out how we’re going to deflect it.” https://www.smithsonianmag.com/science-nature/this-revolutionary-new-observatory-will-locate-threatening-asteroids-and-millions-of-galaxies-180984514/

Do you know how #astronomers are hunting for #exoplanets ? Most of them are discovered with the transit and/or radial velocity techniques.
We developed at #LAM (#laboratoire d'#astrophysique de #Marseille) a web tool that simulate an #exoplanet and show you their photometric and radial velocity signals. Feel free to play with the parameters and see how they change the signals.
