Will asteroid 2023 DW hit Earth on Valentine's Day 2046?! | Night Sky News March 2023

[@leitm3912]

I'm sure we all agree Dr. Becky is the best for easily digestible space content but can we all just appreciate for a minute how dang adorable it is watching her silly bloopers at the end of each video. No matter the content of the full video I always find myself smiling after the bloopers and I wish more content creators took up this idea of showing their bloopers. I feel like Becky is so much more relatable and entertaining because she doesn't pretend to be super professional and "preserving her image" as a scientific content creator and is willing to show us she's still a normal human like the rest of us just happily following our passions on this big hunk of rock.

[@adamc1966]

She definitely has the best bloopers reel, for sure! But she isn't the only top-level explainer. There's also Fraser Cain and Scott Manley, too. 😊

I really love that you cover both what to look for in the night sky in the coming month, but all sorts of interesting astronomy science in the news. Most of the other astro channels I know of do one or the other. AND, you make it all so exciting with your concise but extremely well-explained details. I often put off looking at videos I get notified of until I have plenty of time. With yours, I find the time, which is almost always 'right now!'

[@elmurcis1]

Surprise to see something I (as "citizen scientist") personally have gone "through" to be included in both scientific paper and Sky News topic. Went over around 1,5K of these images up to point where I could trace sattelites, asteroids and gravitational lenses on any wall in sight (not kidding - it took a bit time to "get away" from detection mode)

[@DrBecky]

Amazing! That must be so rewarding to see

Dr. Becky, after watching your shows for all these years I finally went and bought a pair of binoculars. I’m hear in Alaska with no light pollution but also wildlife and wales which is why I bought the binoculars. They are amazing; Celestron 25x100, I can see everything it seems like. Thanks for sparking my interest so much.

Amazing to hear Andy! Sounds idyllic up there - enjoy!

You're not only an excellent scientist, but an excellent communicator! I'd not seen any media hype about the comet other than that we might finally get another highly visible comet. Maybe I keep my news input too specific to have seen the people panicking about the comet, but I loved how you clearly explained all aspects regarding any perceived 'threat'. Well done! What a great episode regarding all of the stories you put together packed with wonderful bits as interesting as they are educational!

I still can't believe that I really observed the beautiful dance of Jupiter and Venus with naked eyes . It's the first time I've observed an astronomical event so deeply and with so much clarity . It was just beautiful and can't be really explained in words . I'm glad , I chose to study Physics .

[@jamesgreenler8225]

Average speed of most meteors is 4 to 7 thousand miles per hour when you see them burning. If anything survives the burn and if you are within 30 miles of one you will hear a sonic boom or even lots of smaller popping sounds and each piece is breaking the sound barrier . You have to be within 30 miles of the event

[@gwtaylor314]

I love these episodes and all your content. I would, as I'm sure many others, love to hear about what you're currently researching. Goals, progress, setbacks, etc.

[@alexz1104]

Another great episode from Dr Becky. There are many asteroids which have yet to be identified, if you are interested in helping to identify some, you can have your computer analyze telescope data in the background for the Asteroids@home project which maintains a public database of known and suspected asteroids. Very cool project.

[@glendownton]

Hello from Western Australia, and yes, Exmouth has been booked solid since forever for the eclipse!

[@zztops489Y]

Dr Becky was wrong about a total eclipse and the time of totality. You *can* look up without protection once totality occurs. If you keep your protection on, you will most likely miss Baily's beads, as well as the mind numbing corona. It's a surreal moment, a moment you will never forget. I know. We had a total eclipse here in 2017. Most incredible thing I have ever experienced. And, of course, get ready for that explosion of light the second the eclipse ends, obviously.

[@richardcurran621]

Always great hearing from you. Very well explained.

[@MaryAnnNytowl]

This always reminds me of the program waaaaaaay back in the days of PBS' Jack Horkheimer: Star Hustler/Star Gazer. In case anyone is wondering, this is a high compliment from me! Thanks for all you do, Dr. Becky. 😊 Keep looking up! ❤️❤️

[@BlaTaN]

I have to commend and thank Dr Becky for the shoutout of the southern hemisphere and the forecasted solar eclipse and also for mentioning the view of the meteor shower being almost non-existent except for maybe a few 'wanderers'. A lot of these science/astrophysical video explainers never or almost never mention these well known facts about the difference in the sky of both hemispheres. I again have to THANK Dr Becky for clearly explaining and pointing this out. Great work :)

[@EmeraldHillsSkies]

Dr. Becky, you mentioned in passing that the nebulosity surrounding M45 was left-over from formation, but don’t i recall a study in which some measurements implied that M45 was merely passing THROUGH existing gas clouds and dust?

[@ariedekker7350]

Thanks young lady, I had a great time again. Greeting from the Netherlands.

[@rosellabill]

Hi Dr. Becky. I just wanted to say Thank You for all that you do. I hope your projects all work out. You put up a video on how the weather interfered in the project. Is this common with all sciencetists? You cannot control the weather. I hope you have a nice Weekend and again. Thanks

[@jackvos8047]

It isn't a problem for all scientists at all. It is a problem for astrophysicists because clouds obscure the sky making terrestrial telescopes useless until they have passed. Meteorologists on the other hand would have nothing to do without weather to study.

I can’t believe the team that named the JUICE mission, didn’t add a “S” to the end of the mission name. Since the probe is going to around multiple moons of Jupiter, they should have added the word(s) satellite, system, or something along those lines. I am going to be watching the launch and looking forward to the findings this mission finds.

[@snigwithasword1284]

If our best argument for dormancy is we just haven't seen any activity on Olympus Mons that's flimsy AF. The vast majority of terrestrial volcanoes go decades or centuries between eruptions, including plenty of hotspots like Mauna Loa.

[@SpaceCadet4Jesus]

Glad to see changes on Venus were now observed. Previous galactic news said a new Hilbert's Hotel was going up near a vacation vent on Venus. That oughta do something good for the depressed economy on Venus.

NASA and SpaceX are in discussions regarding a Hubble orbit boost to bring it back to its original operational orbit. This will be above the current satellite constellations so will remove the current issue. Probably. Hopefully they can pull this off :) Great channel by the way

[@jasonsumma1530]

Would we have any estimate on how bright the nova\supernova would be of the Wolf-Rayet 124? Is there any to know the energy output? I always assumed that Mercury and Venus are the hot planets they are due to being so close to the sun. I wonder if the sun is also effecting the volcano activity with adding more energy to the surface. With all of those private satellites in the lower atmosphere, I wonder what happens when we finally get tagged by a solar flare.

Dr Becky, my understanding of the apparent nebulosity surrounding the stars of The Pleiades is it is the result of a foreground nebula located at roughly half the distance to the cluster. So it is not the remnants of gas from the formation of the stars themselves.

Couldn't some other explanation, like seismic activity, explain the change in shape of the vent on Venus? Did they try to rule something like this out?

[@osmosisjones4912]

Most extinct volcanoes are empty tubs . But Olympus mons is full to the top. . It looks like it cooled rapidly and might have come directly from the mantle

[@glenchapman3899]

Well the top sticks out through the atmosphere so the cooling would have been pretty quick

[@MelindaGreen]

FYI, it's perfectly safe to look directly at an eclipse *during totality*. At that point you can even use binoculars and view the incredibly beautiful solar corona. Of course be aware of the length of totality in your area, and look away as soon as you see the Bailly's Beads as that is when totality is ending. The dynamic range is incredible and cannot be reproduced in photographs or in any other way, so don't miss this incredible spectacle if you get the chance.

Your previous video showed how Hubble could be pushed out to counteract the orbital decay. Why can't it be pushed out far enough to get outside the satellite shell? I'm sure there's a good reason - just don't know what it is?

[@Shortstuffjo]

Why can some sort of code not be written to make telescopes "look out" for satellite trails crossing their field of view while doing an exposure? The telescope could then just automatically not save those seconds in which the satellite is in view. A couple of seconds out of minutes of exposure time could be a worthwhile trade-off. This seems so simple to me though that there is no way it hasn't been thought of and so there must be a reason why it hasn't been adopted. Could someone with more knowledge give me the short and sweet of it please? I've wondered about this for a while. Thanks.

Can you explain why the first videos of the moon landing are blurry?

[@jmonay]

Love your videos! Regarding the asteroid I have a probably pretty basic question - how fast is it going? and how much does that matter? (besides the obvious relation to the strength of the impact).I know that you don’t lose speed while travelling in space so I was a wondering if there’s a huge variation in asteroid speed? Do the asteroids from outside the solar system have some sort of common range of velocity? I’m just imagining an asteroid that’s shooting out from a supernova etc and how that compares to asteroids already in own asteroid belt. Also conversely, I know the asteroids in the asteroid belt are continually slowing down due to the suns gravity(at least I think that’s what happens, please correct me if wrong), but how slow (or fast) do they get before they can’t fight the gravity any more and break orbit? Last question, on large timescales will the asteroid belt eventually fall towards the sun or something else happen? I may be way off on some of my assumptions so please correct anything I got wrong!

[@MountainFisher]

Keep in mind that the Pleiades does not look nebulous, those are long exposure photographs and I do not understand why they show them like that. Now with a very good telescope with very good optics and at least an aperture of 130mm (5") or higher you can spot just a little nebulosity around the bottom stars. It is just a little and you won't see it in light polluted skies near a city, also to fit the whole star cluster into the field of view you need a wide angle eyepiece suitable to your scope or use lower magnification. I think they are awesome to look at even with no nebulosity. There are many open star clusters, but few match the beauty of M45 the Pleiades, in Japan it's called Subaru and that is the pattern you see on the car by the same name.

Sometimes they shoehorn the acronym by pre-choosing a funny word or phrase and forcing the abbreviations. Take STEVE, for example. The Aurora phenomenon was originally called that as a reference to the movie Over the Hedge, but they later forced the acronym by making the letters stand for Strong Thermal Emission Velocity Enhancement.

HEY!!! What about The Arecibo Observatory??? They mapped Venus too!

[@Dragrath1]

Given some of the observations from Venus Express namely the sulfur dioxide spikes the thermal hotspot and the young lava flows which were spatially and temporally consistent within the resolution limits there has been pretty good evidence for volcanism. In fact work looking at chemical erosion from carbon dioxide on volcanic rocks under Venusian conditions (high pressure high temperature high saturation of carbon dioxide etc.) which suggests that chemical alteration of basalt is a very rapid process (i.e. on the order of weeks to months). This means that the chemical signature of basalt should be converted to magnetite fairly quickly thus the detection of basalt from these presumably young flows suggests the lava flows in question were not just young but extremely young i.e. quite potentially still active. Technically we can't say Mars isn't volcanically active rather its dying but not dead yet. Olympus Mon's last significant eruption was only 2 million years ago practically yesterday astrophysically speaking. We have seen tremors associated with movement of magma deep down. Many volcanoes on Earth go many thousands to even tens of thousands of years between volcanic eruptions so is a bit tricky to say a world is volcanically dead based on our limited observational window. Still is much much less active than Earth or presumably Venus. If anything this result best describes the significance that data analysis limitations and biases affect what information we can extract from scientific data.
