Spot the Moon and the Pleiades: This Week in Astronomy with Dave Eicher 7/1/2024
The best of the solar system and our galaxy’s deep-sky objects make a joint appearance in our sky this week, as the Moon slides by the Pleiades (M45). In the early morning sky of July 2, observers in the Americas will see a slender, waning crescent Moon just a few degrees away from the Pleiades open star cluster. (The two objects are at their closest a few hours later, meaning observers in eastern Asia and Oceania will see the pair similarly close to one another in their early morning sky of July 3.)
You’ll also be able to spot a pair of nearby planets - Jupiter will be below and to the left of the Moon, shining at magnitude -2 just above the horizon, and Mars will be shining at around first magnitude just above and to the right of the Moon. Farther past Mars along the ecliptic, facing southeast, will be Saturn, also glowing at first magnitude. This is a great chance to see the solar system in action - and the galaxy beyond.

The Whirlpool Galaxy (M51) is one of the gems of the springtime evening sky - a bright, gorgeous face-on spiral galaxy. With an 8-inch telescope under a dark sky, you can begin to see the spiral structure of its star-forming arms; larger scopes will make the arms more obvious. Due to those attributes, M51 is also an important object in the history of astronomy. When Irish astronomer William Par...
How Markarian 205 nearly broke the universe: This Week in Astronomy with Dave Eicher 5/6/2024

NGC 4319 and Markarian 205 are a pair of objects with a lot of lore and history. NGC 4319 is a spiral galaxy about 77 million light-years distant, while Markarian 205 is a quasar about 1 billion light-years away. But in the 1970s, the astronomer Halton Arp became convinced that these two objects were actually physically connected, and lay at the same distance. If that were true, it would have m...

Great initiative Celestron. Congratulations and well done.
So much credit is given to Newton and Galileo in school curriculums when it comes to astronomical history. Not enough is said about Copernicus and his revolutionary discoveries/theorems.
excellent presentation!
Like a boat or maybe a forklift :)
Fake bs
Everybody knows the Moon formed when the Swiss threw a giant chunk of cheese into space.
No love for Enceladus.
The history of the discovery of the Milky Way bar is richer than presented here. In 1964 de Vaucouleurs, using his deep knowledge of other galaxies and the known measurement of non-circular motions in the inner Milky Way by radioastronomers in 1950's, proposed than these motions were caused by a stellar bar. In 1991 using better radioastronomy data and balloon infrared photometry from Matsumoto et al. (1982) , Blitz & Spergel showed that the observed left--right asymmetry of the central region was compatible with a stellar bar. In 1992 Withelock concluded the same from the distribution of Mira stars. Many other authors arrived to the same conclusions in the same decade, in particular from the IRAS and COBE satellites infrared observations, way before the Wisconsin University team in 2005 with Spitzer satellite data.
what a movie, Kubrick was just a genius!
Big Rip here we come.
Always love it when people compare astronomical sizes to relative things here on Earth that are more easier to picture mentally.
Your full of bull because there is no water no rain clouds to bring rain so water yhea you a little fruity 😂
Thanks for all the information.
For starters nasa has a ton of cameras and actual footage that’s not low res. Next thing is how short the video is. And lastly why focus on Apollo 17 when we have Apollo 60 with better cameras and more proof. There is only so many rock samples you can examine what’s the real mission
You mean Michael Bay had nothing to do with an explosion? Impossible.
Just in case you haven't noticed, everyone is laughing at this goofy video of fake "moon landings", time to take down.
LMAO, at 6.58 is just the alleged front of the rover with a movie in the background
But they didnt really go.

Well, I was convinced of that, but he also convinced me of how he returned to Earth again because he went with a space rocket and the momentum.
Everyone knows it was really a giant brain that killed the dinosaurs. Futurama tells the real truth.

This is real. They are actually on the moon.
Thanks, Dave, I am a brazilian subscriber since 1984.
Kinda wish this video had gone into carbon dating and how it actually is pretty useful and accurate despite what some uneducated individuals say.

I always love when astronomical phenomena can be replicated here on Earth.
I don't think enough scientists talk about planetary nebulae.
What Engine or Batteries Did they Use to POWER the Rover? They Travelled for 17.5 Miles. What did they use to Recharge the battery? How big was this Battery pack?
The Lunar Roving Vehicle used two 36-volt silver-zinc potassium hydroxide non-rechargeable batteries developed by the Eagle-Piche company. Take care
They had a charge capacity of 121 A·h each (a total of 242 A·h), yielding a range of 57 miles (92 km).These were used to power the drive and steering motors and also a 36-volt utility outlet mounted on the front of the LRV to power the communications relay unit or the TV camera. LRV batteries and electronics were passively cooled, using change-of-phase wax thermal capacitor packages and reflective, upward-facing radiating surfaces. While driving, radiators were covered with mylar blankets to minimize dust accumulation. When stopped, the astronauts would open the blankets, and manually remove excess dust from the cooling surfaces with hand brushes.
@@viktorm3840 They weren't driving on Earth.
she's cute, and the only reason i stuck around. :)
I can only hope I'm there to see the end somehow.
What is the upside down umbrella antenna doing exactly? Bouncing around like that the whole time, what is it actually transmitting / receving to or from? No doubt I will get insults instead of answers from the faithful.
because gravity on the moon acts in reverse the rain falls upwards.. so they mounted the umbrella upside down.... obvious even to a 5 year old child..
I've always loved the idea that the multiverse is a highway of infinite lanes and you're just one car. Every time you make a choice, another car splits off of you into one of the different lanes. Infinite choices, infinite possibilities.
❤Thanks
Just because there's evidence that backs a theory, doesn't necessarily make the theory true. There is zero proof that super solids occur naturally (the only one humans have ever seen was artificially created), and even if they do, I personally don't but into your theory that you try to state as fact.

Looking forward to this. I hope I have clear skies.
You know those geese were definitely wondering what Eicher was doing running around like that.
What should I do? What should I do with what I have? What should I take away?
FINALLY someone is talking about this! The opinion of planetary scientists should supersede the IAU. Dwarf planets and large moons are planets! 👍🏻👍🏻
The problem with that line of thinking is that there are a LOT of planetary scientists, myself included, who think classifying Pluto et al. as dwarf planets is a good thing. While the IAU's definition isn't a good one, the line needed to be drawn somewhere because labeling almost literally everything spherical in a system as a planet is just silly.
@@MamoruChiba1That’s not silly at all. What’s silly is defining a dwarf planet as NOT a planet. What’s silly is thinking we need to limit the planets of the Solar System to a small number. It’s not silly to define every lump of rock as an asteroid, it’s not silly to define every celestial body that does nuclear fusion as a star, and it’s certainly not silly to define everything spherical with sub-stellar mass as a planet. That’s just the data, get used to it. You don’t need to draw an arbitrary line anywhere. The IAU definition is ignored near unanimously by planetary scientists. After Phil Metzger did an enormous literature search of over 10,000 scientific papers, he found ZERO papers that use the IAU definition. Planetary scientists are voting with their feet and it’s clear the Emperor has no clothes. The IAU definition has been an embarrassment to science.
"Theres no doubt about those mountains being there" - Huh? Who or why does someone say something like that?
