  Asteroid bigger than the Statue of Liberty will fly past Earth on Christmas Day, NASA
Posted by: Trunk - 12-24-2020, 10:49 PM - Forum: General Discussion - No Replies

  • Asteroid measuring up to 690 feet in diameter set to pass tomorrow, NASA says

  • This is over twice the length of the 305-foot-tall Statue of Liberty in New York

  • The asteroid (2014 SD224) will be travelling at more than 22,000 miles per hour
An asteroid bigger than the Statue of Liberty will fly past Earth at 8:20pm GMT on Christmas Day, according to data from NASA's Center for Near Earth Studies.

The asteroid, called 2014 SD224, will come within 0.02019 astronomical units, or nearly 1.9 million miles, from the Earth's surface.  
2014 SD224 has a diameter anywhere between 302 and 690 feet (92 to 210 metres) – meaning it could be more than twice the size of the Statue of Liberty (305 feet) or bigger than Salisbury Cathedral (404 feet). 
As 2014 SD224 flies past Earth, it will be travelling at a speed of 10 kilometres per second or more than 22,000 miles per hour – roughly 30 times the speed of sound. 

Despite being around eight times further out than the Moon, the asteroid is classed as a near Earth object (NEO) and is being tracked by the space agency. 

Although 2014 SD224 – which can be tracked on NASA's website – is at a distance of 1.9 million miles away, this is relatively close in astronomical terms. 

For this reason, 2014 SD224 is defined by NEO, although it's not expected to do damage. 

NEOs are an asteroid or comet whose orbit brings it into or through a zone between approximately 91 million and 121 million miles (195 million km) from the Sun, meaning that it can pass within about 30 million miles (50 million km) of Earth’s orbit.

If the object is larger than 460 feet (140 meters) across, it is considered a potentially hazardous object (PHO).

'NEOs are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth’s neighbourhood,' said NASA.

'Composed mostly of water ice with embedded dust particles, comets originally formed in the cold outer planetary system while most of the rocky asteroids formed in the warmer inner solar system between the orbits of Mars and Jupiter.

'The scientific interest in comets and asteroids is due largely to their status as the relatively unchanged remnant debris from the solar system formation process some 4.6 billion years ago.'

According to publicly available NASA data, there have been 24,629 NEOs discovered, as of Tuesday. 

It is estimated that there are about 25,000 near-Earth objects (NEOs) larger than 460 feet (140 metres).

And there are also an estimated 1,000 NEOs larger than 3,280 feet (one kilometre), highlighting the need to keep track of these space rocks.

On average, Earth is hit by a football pitch-sized rock every 5,000 years, and a civilisation-ending asteroid every one million years, according to NASA's Near-Earth Object Program.

Question 'Wow!' Again? SETI Mystery Signal Could Long Puzzle Astronomers
Posted by: skitzo - 12-23-2020, 09:05 PM - Forum: General Discussion - No Replies

A recently detected SETI signal could end up being this generation's version of the famous "Wow!" signal of 1977: an intriguing mystery that keeps astronomers guessing for decades.

In May 2015, a team of researchers using a Russian radio telescope spotted a strong radio signal coming from the vicinity of the sunlike star HD 164595, which lies 94 light-years away from Earth.

The signal is consistent with something an alien civilization might send out, astronomers have said. But that's just one scenario, and not the most likely one, researchers cautioned; the signal may also have resulted from a natural celestial event or terrestrial interference of some sort.

Without a follow-up detection or confirmation, humanity may never know the signal's true origin, said Seth Shostak, a senior astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California. (Shostak was not part of the detection team.)

"If they can't find it again, and if we [at SETI] can't find it, all we can say is, 'Gosh, I wonder what it was,'" Shostak told Space.com.

That's pretty much all that astronomers can say about the Wow! signal, a 72-second-long event picked up by the Big Ear radio observatory at The Ohio State University in August 1977.

The 1977 signal received its name after a volunteer astronomer named Jerry Ehman wrote "Wow!" on a computer printout of the signal's transmission record. Ehman made the comment after finding the radio signal was 30 times stronger than background emissions.

Astronomers never discovered any evidence linking the Wow! signal to an alien civilization, and, despite recent efforts from the SETI Institute, a repeat detection of that signal has not been made. Researchers did conclude the signal was coming from the direction of the constellation Sagittarius.

"There are going to be signals that you see once and don't see again," Shostak added. "It's like people who see ghosts. If you see it once, but when you go back, with a camera and all that, it's not there, what do you conclude from that?”
The May 2015 and Wow! signals are analogous in another way, Shostak said: Both seemed to appear and then disappear quite quickly. This doesn't seem consistent with a signal from an orbiting satellite, which would be in range of the radio telescope for longer stretches, he said.

"The thought is: Well, that wouldn't be a satellite. A satellite would be on, and maybe it'd be on for a minute or something like that. It wouldn't just go up and down right away," Shostak said.
Astronomers know that HD 164595 houses a roughly Neptune-mass world, but this close-orbiting planet is likely far too hot to host life as it exists on Earth. But it's possible that other planets lie undiscovered in the system, Shostak said.

The team of astronomers who spotted the May 2015 signal apparently studied the HD 164595  system 39 different times but made just the one detection, Shostak said. The detection team has not yet published a study of its findings. Instead, the researchers plan to discuss the signal next month at the 67th International Astronautical Congress (IAC) in Guadalajara, Mexico.
The detection of the May 2015 signal was made public on Aug. 27 by Centauri Dreams' Paul Gilster, who wrote that one of the astronomers on the detection team forwarded him the IAC presentation.

In hopes of learning more about this possible extraterrestrial signal, astronomers from the SETI Institute focused the Allen Telescope Array in California at HD 164595 Sunday night (Aug. 28) and Monday night (Aug. 29), Shostak said.

Lightbulb Most Popular Dates for Sightings (as of December 2020)
Posted by: skitzo - 12-23-2020, 07:27 PM - Forum: General Discussion - Replies (3)

Another top 20 list. This one's a bit more interesting. You have dates you'd expect to see more sightings with firework celebrations (Fourth of July, New Years Eve). However this one has some strange dates bubbling to the top. I'd love to hear if anyone has any insight to what may have happened on these dates to cause a spike in reports. There is no concentration of cities within the dates.

I'll start dropping out interesting aggregations of data from the databases from time to time. This one unfortunately isn't too interesting.  Big Grin As you'd expect major US cities bubbled right up to the top. 

The first place it gets interesting is at position 32. Canton, Ohio shows up as an outlier. A smaller mid-sized city showing up above much larger population centers.

  1. Los Angeles
  2. Phoenix 
  3. New York 
  4. Las Vegas 
  5. Portland 
  6. Montgomery 
  7. San Diego
