Catalina Sky Survey

CSS is the worlds' most productive near-Earth asteroid Survey. CSS is a #NASA funded project based at the University of Arizona.

BIG NEWS! CSS observer Jacqueline Fazekas has just discovered a small meteoroid that will harmlessly impact with Earth's atmosphere in about 8 hours over the Western Pacific. The object (called CAQTDL2) is small, a few feet in diameter. Attached are the discovery images.

@tony873004 It's actually a comet. It has been on the PCCP since the day of the discovery :)

We're excited to announce our new program on @the_zooniverse , If you've ever wanted to be an asteroid hunter or planetary defender then please come help us keep the planet safe at https://t.co/DhROTrubBA

The solar activity has been intense enough that the #AuroraBorealis can be seen down here in Tucson, it was a lovely show captured by our Mount Bigelow all-sky camera!

Sleep soundly on this silent night as Catalina Sky Survey keeps eyes on the sky through the new year. Wishing you all happy holidays from Mount Lemmon!

This morning at 8:26:59 UT a #asteroid disintegrated over the city of Brantford Ontario. The object (2022 WJ1) was 1m in size & caused no reported damage. Discovered by CSS observer David Rankin, it was quickly identified as a small & harmless impactor by #NASA's CNEOS

Last night we were able to capture this fireball on our sky cams, a small object like this poses no threat to Earth. We still love to see them though!

(1/2) This week we had a great time as the weather finally started to clear! we were able to discover ~87 new NEOs as well as grab some great pictures along the way. Observer David Rankin captured both the Rosette nebula and an exploding meteor using our primary survey telescope!

Today we call your attention to the WGSBN bulletin which features asteroid number 47708 named after Jim Hamilton, who was known for curating an email newsletter for Astrophotography before his passing in 2021. You can find the original citation at https://t.co/OtfckcdfCC

[Catalina Sky Survey @catalina_sky]

Today's look at the WGSBN Bulletin gives us many asteroids named for many great people. One of which being asteroid number 25589 for @Danicamckellar an amazing actress and author helping to bring women to STEM and fun to mathematics check it out at https://t.co/78DXHucnnf V2#7

While the telescope is away, harps will play! As our 1.5m telescope's primary is off for re-aluminizing Operations Specialist Alessandra S. plays "Stella Splendens" taking advantage of the domes acoustic properties! https://t.co/zyYoiakWiy

One of the asteroids discovered by CSS is going to be visited by a spacecraft!

The #asteroid target for this @NASA mission was first observed by @catalina_sky, which supports NASA's search for near-Earth objects for #planetarydefense!

2021 has been a great year for Planetary Defense. Some highlights include the launch of the Dart mission and reaching 3.000 near-Earth asteroid discoveries in one year by the Planetary Defense community. CSS found 1.403 NEAs in 2021. Here is to an even better 2022!

Here at @NASA, we're on the job to find & track near-Earth objects…but have you ever wondered WHERE the known objects are? Through a new 3D real-time visualization tool, you can now explore asteroids and comets that approach Earth’s orbital neighborhood: https://t.co/UPt01yi54G

Get to know the discoverer of C/2021 A1 (Leonard)! We just published an interview with Catalina Sky Survey observer Greg Leonard.

Skywatching Tip: #CometLeonard, discovered by @Catalina_sky member Greg Leonard while searching for near-Earth objects for @NASA, is predicted to peak at a brightness that will probably require binoculars to spot it. See when and where to look up: https://t.co/9lkPpVsO8u
