In this month’s Night Sky News episode we’re chatting about how to spot the conjunction of Mars & Jupiter, the Moon occult Saturn, and the Pleiades meteor shower. Plus in space news we’ll be chatting about the intermediate mass black hole that’s been found in our galaxy, right in the mass gap where we’ve never found a black hole of that mass before, ESA’s recent Ariane 6 launch, JWST’s look at the famous Penguin galaxy, plus the asteroid Chiron turning into a comet.

👩🏽‍💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.

    JWT is something else. The pics its been sending back are jaw droppingly awesome
  • @thomasdjonesn
    That LISA project is so cool, I've been following available developments since the idea was advanced. I hope I'm still around when they start getting data from it ❤
  • Not sure whats more important to myself, the news you give, or the bloopers you admitt to. Both are vastly intresting to myself. Stay True to your calling, it is so refreshing!
  • I’d love to look up. My telescope would love to look up, but we see is clouds. 😄

    8:13 IRT the Ariane 6 launch, considering the second stage APU didn't function on the 2nd relight, it cannot deorbit the 2nd stage, release its last two deorbit test satellites and it is now space junk, I think characterizing the mission as successful is an overstatement. The reliability of the APU is critical to the 2nd stage relight capability. Clearly that function will have to be fixed with certainty before any 2nd stage relight missions are attempted. ESA showed a positive face at their press briefing, however, I am certain the disappointment is deep. 20:50 Did you hear the report that there has been detected an intermediate sized black hole in the IRS 13 star cluster located in the Galactic Center? The distance between the IMBH in IRS 13 and Sgr A* is approximately 3.6 light-years (or about 1.1 parsecs). The estimated IMBH's size is 1,300 to 10,000 times that of the Sun. It appears to be gravitationally bound to Sagittarius A,

    If Ron goes to collect the Mars samples, I hope he's been practising his leviosa
  • Unfortunately, a problem with the APU on the upper stage prevented the engine from restarting when required. Still, the Ariane 6 launch was mostly successful.
  • @mrstevo32100
    Rendezvous- Ron 😂 love it, you heard it from Dr. Becky first!!
  • @Marwolaeth01
    Ooh I need to get my eyes seen to. For 8 seconds there I thought we had a chance to see Alderaan
  • Thanks for the mention of the program you were using, I was wondering what it was. Stellarium.
  • @undefined40
    "The Ariane 6 Launch went off without a Hitch" Yea, the launch itself went well. However, once up there, the upper stage was unable to ignite it's engines again and initiate reentry.
  • @picksalot1
    Interesting that you mentioned a "focus boost" when switching between sitting and standing at your desk. I noticed the same thing when I started using a standing desk. I feel about 10% smarter when standing. It took over a month for me to comfortable using an optional Standing Desk, but it was worth it.
  • I usually FF thru commercials, but I’m going to look into one of these ‘elevator’ tables. 🤔😁 Thanks Dr. Becky! 👍
  • @davehall8584
    absolutely brilliant content and presentation in this one Dr Becky!
  • @Ryan_gogaku
    21:30 I was very surprised to learn that x-ray emissions from a potential IMBH wouldn't be expected in a globular cluster. Surely there must be other ways of looking for it, though, right? Even for Sagittarius A*, there was the sort of "smoking gun" time-lapse showing stars clearly orbiting around something we couldn't see. With that many stars in that compact of a space, and with so much less dust obscuring our view, surely there has to be a way to get more "direct" evidence of this, right? (Also wondering if a tidal disruption event would be possible)
  • I agree Dr. Becky, your history of most distant galaxies is one of your best! It's one of those videos I didn't know I wanted. Among other things, It really helped to contextualize the frequent "most distant" galaxy news we get. Of course, all your videos are terrific! ♥
