I decided to try to get a photo of #Comet #Nishimura this morning. Haze, smoke, clouds, and the glow from Omaha just about thwarted me, but it looks like I managed to capture #CometNishimura in the last photo before I ran out of darkness.

#BBC 📆 2021 In 📆 1992, two #astronomers 🔭 discovered the #KuiperBelt. In 📆 2016, two professors of #PlanetaryScience at #Caltech proposed a massive #planet 🪐, between five and 10 times the size of Earth 🌏. https://www.bbc.com/future/article/20210216-the-massive-planet-scientists-cant-find

The Vera Rubin #Observatory 🔭 will start searching for long period #comets ☄️ coming from the #OortCloud when it is completed 📆 2023. https://www.bbc.com/future/article/20210618-the-solar-systems-icy-shell-contaminated-by-other-stars 🗺️ https://graphhopper.com/maps/?point=Vera+Rubin+Observatory&layer=Esri+Satellite

#OortCloud #comet up to 230 miles wide, traveling 1 #AU per year passing by in 📆 2031 “#Comets ☄️are like #cats, you never know what they’re going to do.” https://www.smithsonianmag.com/smart-news/giant-comet-oort-cloud-will-pass-sun-2031-180978048

#SCMP 📆 2 Feb 2023 : Last seen by the #Neanderthals: ‘Green #comet’ observed by #astronomers in #Greece 🇬🇷 https://youtu.be/gbcwK8KiBSY

#GreenComet 📆 Wednesday, 1 February: At its closest point to #Earth, the green #comet ☄️ will appear bigger and brighter. It will be visible near the constellation Camelopardalis https://www.independent.co.uk/space/green-comet-2023-where-to-see-b2272560.html

📆 February 1 : The last time the #comet passed #Earth was during the Upper Paleolithic period, when #Neanderthals still roamed Earth https://phys.org/news/2023-01-year-comet-visible-naked-eye.html

#GreenComet

1/ Today's #generativeart tweet, theme is the once in a lifetime green #comet C/2022 E3 which will make its appearance over Earth today. All images generated via #stablediffusion v2.1.

A bit of Moondance for January, 2023. January is a busy month with #Earth passing through #Perihelion on the 4th, and a nice view of the #SolarSystem later in the month. #Mercury is setting, but will rise as a morning object late in the month (look to the east around before dawn after the 21st). The remaining visible planets can be seen in the evening sky. You can find #Mars, #Jupiter, #Saturn, and #Venus (from east to west). #Neptune and #Uranus are also up, but require binoculars or telescope. Look for a very close conjunction between #Venus and #Saturn on the 22nd. The two will be separated by ~0.3˚. The #WaxingCrescent #Moon will pass by the pair, giving a nice pattern on the 23rd. The Moon will pass by Jupiter on the 25th, Uranus on the 28th and Mars on the 30th. At the end of the month look for #Comet C/2022 E3 (ZTF) in the north, near $UrsaMinor. The comet will require binoculars to see. I have attached a sunrise-transit-set table exported out of #MICA from #USNO.

Asteroid Strike Simulator

“Hundreds of thousands of asteroids lurk in our solar system, and while space agencies track many of them, there’s always the chance that one will suddenly appear on a collision course with Earth. A new app on the website Neal.fun demonstrates what could happen if one smacked into any part of the planet.
Neal Agarwal developed Asteroid Simulator to show the potentially extreme local effects of different kinds of asteroids. The first step is to pick your asteroid, with choices of iron, stone, carbon, and gold, or even an icy comet. The asteroid’s diameter can be set up to 1 mile (1.6 kilometers); its speed can be anywhere from 1,000 to 250,000 miles per hour; and the impact angle can be set up to 90 degrees…”

"The bad news is #NASA estimates that it tracks only about 40 percent of the #asteroids ☄️#large enough that they could cause calamity if they were to hit #Earth" https://www.washingtonpost.com/technology/2022/10/24/nasa-asteroid-telescope
