A solar eclipse, by definition, must happen during the day. The moon passes between the sun and the earth. The moon’s shadow is cast on the earth.

If you have clear skies tonight, you can get a good look at the Red Planet Mars tonight. At 12:45am CDT, Mars is in the Southern sky, about 45 degrees up from the horizon. It's the closest Mars has been to the Earth in 15 years (since 2003).

Title: Mysterious Signals From Space
Post by: albrecht on August 01, 2018, 09:04:59 PM
https://www.cnet.com/news/new-radio-telescope-picks-up-mysterious-signal-from-space/

"The Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia detected the first-ever FRB at frequencies below 700 MHz on July 25, a signal named FRB 180725A.

As you might guess, FRBs are milliseconds-long bursts of radio emissions that come from some unknown source across the universe. They're one of the newer cosmic mysteries around, having been first detected only about a decade ago. Possible explanations include bursts from magnetars, exploding black holes, and yes, highly advanced alien civilizations."

Some really amazing graphics in this one. Now if you really want to get dizzy imagine this helix with paths of the Voyager spacecrafts as the trajectories were being bounced off the outer planets. They had this calculated out to Neptune to a matter of seconds to what was calculated a decade earlier. To top it off each planet had a different angle to the plane of the ecliptic so being even a fraction of a degree in error would have been a show stopper.

Obviously they use sidereal time to plan reception with tracking antennas.

Maybe this will springboard the US return to the Moon. What most folks don't know was that Apollo and the space race was a product of the Cold War. Without this history, the Moon probably would not have visited by more than a dozen or so probes at this point.

Another picture from the Chang'e 4 Moon lander from the Von Karman crater on the lunar far side.(Taken just before the one above) The brown tint is not an anomaly. Various moon rocks and soils have varied from white, grey, brown, and light green and sometimes this is enhanced by lighting and the viewing angle.

Title: Re: Astronomy and the Heavens / Supermoon
Post by: Up All Night on March 19, 2019, 10:43:00 PM
Sky-watchers in the Northern Hemisphere will get to see a cosmic triple play on March 20, 2019 as a “super worm moon” lights up the vernal equinox. According to astronomy website EarthSky.org, a full moon has not landed this close to the first day of spring since the year 2000, and the two celestial events won’t happen less than a day apart again until 2030.

Because the moon’s orbit is egg-shaped, there are times when it is at what astronomers call perigee, or its shortest distance from Earth, and times when it is at apogee, or its farthest distance from Earth. And because the size of the moon's orbit varies slightly with each lunar cycle, perigee is not always the same distance from month to month.

At 3:45 p.m. ET (19:45 UT) on March 19, 2019 the moon will be a mere 223,309 miles away from our planet, making for an especially close perigee.

Then, at 9:43 p.m. ET on March 20, 2019 (1:43 UT on March 21), the moon will officially reach its full phase. As a result of these combined events, the full lunar disk will appear 14 percent larger and 12 percent brighter than usual—a spectacle widely known as a supermoon.

The equinox supermoon will be the final one for 2019, which already saw supermoons fall on January 21 and February 19. But the year may have saved the best for last, given the coincidental timing with the March equinox at 5:58 p.m. ET (21:58 UT) on March 20—less than four hours before the supermoon arrives.

I got to see a string of SpaceX Starlink satellites pass by over here on the West Coast.  It was pretty cool.  I must have seen about thirty or forty of them.  It was around 9:25 pm Pacific time and it was dark outside, but the satellites were up high enough to reflect the rays of the sun and that's why they were visible for nearly half an hour.  At first I saw one after another pass by above, but then I saw a group of four in a diamond shape formation.  I also saw several of them catch the sunlight just right and they became bright bursts of light for an instant.  Near the end, two of them went by and they were close together.  It was a fun sight and from what I heard, they will be passing by overhead tomorrow night as well, 9:25 again for my sector, though it might be a different time for other West Coast locations.  Check your local paper, they might have some information, plus there are some tracking sites like this one:  https://findstarlink.com/

I wonder.  Also, those last two that were close together.  One wasn't behind the other, they were both running side by side.  From what I can ascertain, they are supposed to be a string of satellites, but I definitely saw a group of them shaped like a diamond, and also those last two that were running parallel to each other.  I read that they are equipped with ion engines that allow them to be adjusted for higher orbits.  When I was watching them pass by one after the other, they didn't look like a string.  They were all traveling in the same direction but some seemed to have slightly wider orbits than others.

I got to see a string of SpaceX Starlink satellites pass by over here on the West Coast.  It was pretty cool.  I must have seen about thirty or forty of them.  It was around 9:25 pm Pacific time and it was dark outside, but the satellites were up high enough to reflect the rays of the sun and that's why they were visible for nearly half an hour.  At first I saw one after another pass by above, but then I saw a group of four in a diamond shape formation.  I also saw several of them catch the sunlight just right and they became bright bursts of light for an instant.  Near the end, two of them went by and they were close together.  It was a fun sight and from what I heard, they will be passing by overhead tomorrow night as well, 9:25 again for my sector, though it might be a different time for other West Coast locations.  Check your local paper, they might have some information, plus there are some tracking sites like this one:  https://findstarlink.com/     

Thanks @Rikki Gins . I'm a stargazer too. I've seen the ISS float across the sky but didn't know about these. I downloaded the app for a reminder. Now when it updates, I just have to hope for clear skies

Here's a natural alignment this weekend

Looking for a fun way to pass the time while social distancing? The heavens will be putting on a free show this weekend, with an ornamental assortment of planets decorating the morning and evening skies.

Weather permitting, you’ll be able to catch the celestial rendezvous all weekend. In the evenings, you can spot Venus, while mornings will offer a lineup of the moon, Mars, Saturn and Jupiter.

Oh nice, @TigerLily.  Would that be the Heavens Above app?  I used to access it years ago but now they want you to log in, so I'll probably do that, as it's a very good site.  Good luck on seeing the 'string' of satellites.  It's a sight you won't forget.

I came across an interesting app that allows you to see what the Hubble space telescope took a picture of on your birthday.  Here:  https://www.nasa.gov/content/goddard/what-did-hubble-see-on-your-birthday

Here is the photo that the telescope took on my birthday back in 2002.  It shows Arp 220, a couple of spiral galaxies that started to collide some 700 million years ago.  They are located about 250 million light-years from Earth.

One of our spacecraft (OSIRIS REx) flew down to asteroid Bennu earlier today, where it got close enough to grab some of the surface with a probe.  It didn't land, it just got the sample and bounced back up.  It will return the sample of asteroid in 2023.

Viewing the Christmas Star on MidWinter Night

Here's something for all you Christians and Pagans and plain ol' stargazers

The Great Conjunction of 2020 will brighten the darkest day of the year as the two giant planets of our solar system draw closer together in the night sky than they have been in centuries.

By chance, the day that Jupiter and Saturn will appear closest for Earth-based stargazers is Dec. 21, the winter solstice, which is the longest night of the year in the northern hemisphere.

The double planet view is also known by some astronomers as the "Christmas Star" because of a belief that the biblical tale of the Star of Bethlehem could have been a planetary conjunction. Although around two thousand years ago, Venus and Jupiter were closest — not Jupiter and Saturn, as is the case for the "Christmas Star" of 2020.

On the evenings of December 15 through 18, stargazers can easily find Jupiter and Saturn moving in conjunction by looking toward the waxing crescent moon in the western sky 45 minutes after sunset, according to NASA's Night Sky Network.

Oh, I'm so happy that you liked the picture, Annie.  I was clouded in too and have to confess that the photo was taken one day late, but still, the planets were pretty close to each other.  Almost everything on the western horizon is closed off to me, due to big houses across the street and even bigger trees.  But I had a brief opening so I took advantage of it.  Jupiter and Saturn will be close to each other in 2040 and 2060, but not as close as they were this December.  We will have to wait until 2080 for them to get really close again.  I can't wait.

Billions of Celestial Objects Revealed in Gargantuan Survey of the Milky Way
NSF’s NOIRLab releases colossal astronomical data tapestry displaying the majesty of our Milky Way in unprecedented detail

18 January 2023

Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects — arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera, built by the US Department of Energy, at the NSF’s Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLab.
