Comet 3I/ATLAS

What is it? 

My most recent favorite theory/assumption/conspriacy is that it's some kind of cloaked alien space ship. 

Thoughts?

Hubble looked at it. It's a comet.

Ah, I will have to go check that out. I looked at the NASA site briefly, but didn't get a chance to read all of it. 

The "cloaked ship" thing just popped up on my social media and I got a kick out of that. Thought of Star Trek.

Nah. It's not as big as they thought too. It looks that way because of all the debris coming off it.

This/ Amazing though.

 Also amazing, it takes the sun 250,000,000 years to circle the milky way solar system. It’s done it twenty times, and has twenty + to go till it burns out and becomes a black star. Glad I’m not going to be around.

I agree.

But I watched Independence Day with my kids last week, so it might just be recency bias.

I've been around the milky way. It gets old after the first few times.

When you say milky way... are you referring to another man's urethra?

Avi Loeb just posted an incredible theory about 3I/Atlas tied to the 1977 Wow signal :

Was the “Wow! Signal” Emitted from 3I/ATLAS?

The “Wow! Signal” was detected on August 15, 1977 as a strong narrowband radio signal by Ohio State University’s Big Ear radio telescope. Its origin was inferred to be extraterrestrial. The latest natural explanation (accessible here) hypothesized that the “Wow! Signal” was caused by a sudden brightening of the hydrogen line emitted from an interstellar cloud, triggered by a strong transient radio source, such as a flare from a highly magnetized neutron star (magnetar).

The “Wow! Signal” originated from the sky coordinates of Right Ascension (RA)=19h25m=291 degrees and Declination (Dec)=-27 degrees.

On August 12, 1977, the interstellar object 3I/ATLAS was at a distance of about 600 times the Earth-Sun separation (AU) — corresponding to a light-travel time of about 3 days. It had the sky coordinates of RA=19h40m=295 degrees and Dec=-19 degrees. These parameters can be inferred accurately given the lack of non-gravitational acceleration for 3I/ATLAS, as inferred in my latest paper (accessible here).

Hence, the “Wow! Signal” was separated by approximately 4 degrees in RA and 8 degrees in Dec from the direction of 3I/ATLAS. The chance of two random directions in the sky being aligned to that level is about 0.6 percent. If the “Wow! Signal” originated from 3I/ATLAS, how powerful was the transmitter?

The detected intensity of the “Wow! Signal” was in the range of 54–212 Jansky with a bandwidth of about 10 kilohertz. At the distance of 600 AU, this corresponds to a source power of 0.5–2 gigawatts, the output of a typical nuclear reactor on Earth.

The “Wow! Signal” was observed at a frequency of 1420.4556±0.005 megahertz, blue-shifted by about 10 kilometers per second towards Earth relative to the central frequency of the hydrogen line. This blueshift is of the same order of magnitude but smaller than expected from the approach velocity of 3I/ATLAS towards the Sun, 60 kilometers per second.

Stay on topic. What do you think about the comet?

[frank 2,348]

Some say a comet will fall from the sky, followed by meteor showers and tidal waves.

Many people are saying that 3I/ATLAS is the Doomsday Machine from Star Trek.  

[Frozenbeernuts 2,372]

I believe it is a comet. Though there are ships all around earth, I don't believe this is one.

NASA will host a live event at 3 p.m. EST, Wednesday, Nov. 19, to share imagery of the interstellar comet 3I/ATLAS collected by a number of the agency’s missions. The event will take place at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Comet 3I/ATLAS, discovered by the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) observatory on July 1, is only the third object ever identified as entering our solar system from elsewhere in the galaxy. While it poses no threat to Earth and will get no closer than 170 million miles to Earth, the comet flew within 19 million miles of Mars in early October.

The event will air on NASA+, the NASA app, the agency’s website and YouTube channel, and Amazon Prime.

Briefing participants include:

• NASA Associate Administrator Amit Kshatriya
• Nicky Fox, associate administrator, Science Mission Directorate
• Shawn Domagal-Goldman, acting director, Astrophysics Division
• Tom Statler, lead scientist for solar system small bodies

To participate virtually in the NASA Live event, members of the media must send their full name, media affiliation, email address, and phone number no later than two hours before the start of the event to Molly Wasser at: molly.l.wasser@nasa.gov. Members of the public also may ask questions, which may be answered in real time during the broadcast, by using #AskNASA on social media.

Assets within NASA’s science missions give the United States the unique capability to observe 3I/ATLAS almost the entire time it passes through our celestial neighborhood, and study – with complementary scientific instruments and from different directions – how the comet behaves. These assets include both spacecraft across the solar system, as well as ground-based observatories.
