For the second time ever, astronomers have detected an interstellar object plunging through our solar system!

But this time, researchers think they know where it came from.
When you rewind Comet Borisov's path through space, you'll find that 1 million years ago, the object passed just 5.7 light-years from the center of Kruger 60, moving just 2.13 miles per second (3.43 kilometers per second), the researchers wrote.

"If you have an interstellar comet and you want to know where it came from, then you want to check two things," he said. "First, has this comet had a small pass distance from a planetary system? Because if it's coming from there, then its trajectory must intersect with the location of that system."
Though the 5.7 light-years between the new comet and Kruger may seem bigger than a "small gap" — nearly 357,000 times Earth's distance from the sun — it's close enough to count as "small" for these sorts of calculations, he said.
While you're here, how about this:
Pressure runs high at edge of solar system
"In adding up the pieces known from previous studies, we found our new value is still larger than what's been measured so far," said Jamie Rankin, lead author on the new study and astronomer at Princeton University in New Jersey. "It says that there are some other parts to the pressure that aren't being considered right now that could contribute."
On Earth we have air pressure, created by air molecules drawn down by gravity. In space there's also a pressure created by particles like ions and electrons!

These particles, heated and accelerated by the Sun create a giant balloon known as the heliosphere extending millions of miles out past Pluto. The edge of this region, where the Sun's influence is overcome by the pressures of particles from other stars and interstellar space , is where the Sun's magnetic influence ends. (Its gravitational influence extends much farther, so the solar system itself extends farther, as well.)
A second interstellar object has been spotted in our solar system
Astronomers spotted an interstellar object passing through our solar system last month. It was only the second time scientists have ever detected such an object and after some intense investigation, the object — now believed to be a comet or comet-like body — was documented and named for the amateur astronomer who first spotted it.
The comet, called 2I/Borisov, was spotted relatively early in its trip through our system, giving scientists plenty of time to observe it. The first round of studies is already returning some interesting findings, including the fact that the object is dumping cyanogen gas (gas that is at least partly made up of cyanide) as it speeds through our home system.
A new paper published in Astrophysical Journal Letters reveals that interesting finding, which was made thanks to data gathered by an international team of scientists using the William Herschel Telescope!

This Time, Astronomers Think They Know Where It Came From For the second time ever, astronomers have detected an interstellar object plunging through our solar system. But this time, researchers think they know where it came from.!! But as seemingly frightening as this discovery seems on the surface, there's very little to worry about for us here on Earth.
Will all 8 planets in our solar system ever perfectly align?
While such images are novel ideas, and while some might wonder if such an alignment would lead to some supernatural event as you see in the movies, it's never going to happen.
* * *
The main reason is because not all the planets are on parallel orbital paths. Some of the orbits are tilted compared to the others.
If such an alignment ever did happen, the gravitational forces reportedly would not affect Earth in any meaningful way. The only two bodies in our solar system big enough or close enough to significantly affect us are the sun and the moon.
This doesn't mean earthlings will never see their seven celestial neighbors sharing the same night sky. The last time it happened was the year 949, according to Science Focus. The next time will be May 6, 2492.
That date will change if astronomers ever identify another planet in our solar system and have to add that to alignment possibilities! 2nd interstellar visitor to our solar system confirmed and ...www.cnn.com /2019/09/24/world/ second - interstellar - ...scn-trnd/...2nd interstellar visitor to our solar system confirmed and named - CNN An unusual object detected streaking across the sky last month was a comet that originated outside our solar system,...!!

Not to change the topic here:
To-scale solar system now orbiting around CBEC
A new cosmic art installation on The Ohio State University campus represents our solar system and bridges the arts and sciences in an astronomical way.
“The Solar System to Scale” comprises 10 mixed-media kiosks that begin with a “sun” kiosk on Woodruff Avenue outside the Chemical and Biomolecular Engineering and Chemistry Building and end with a “Pluto” kiosk near the Chadwick Arboretum Learning Gardens on West Campus. The spacing between the kiosks is a to-scale representation of each planet’s distance from the sun.
The installation was funded by a gift from alumni M. Andrew and Sandra L. Ross . The Rosses had their first discussion with the university about their vision to bring “The Solar System to Scale” to campus in July 2015. The idea came from Andy’s fascination with space as a child, he said, recalling how he looked up to the sky one night and asked his dad how close the nearest star was. Since that point, he’s never stopped trying to grasp the size of the universe.
Voyager Mission Reveals Unexpected Pressure at The Edge of The Solar System
NASA astronomers have used data from the Voyager probes to measure the bustle of particles rippling at the very edge of our Solar System, and discovered the pressure in the distant borderlands of our star is higher than they expected.
The results suggest "that there are some other parts to the pressure that aren't being considered right now that could contribute," says Princeton University astrophysicist Jamie Rankin .
Maybe there are entire populations of particles out there that haven't been taken into account yet. Or maybe it's just a little hotter than anybody figured. The researchers have a number of possible explanations to explore in future research.
While the discovery itself is interesting enough, it's the way they found it that makes for a truly fascinating bit of science.
As plasma in the shape of solar wind emanates from our Sun, it forms a 'bubble' we call the heliosphere. Fourteen billion kilometres away from the star, that wind effectively runs out of steam, as charged particles rapidly slow to subsonic speeds.
