Highlighted by astronomers at the University of Rochester and the European Southern Observatory, the star — nicknamed “Scholz’s star” — has a very low tangential velocity in the sky, but it has been clocked traveling at a breakneck speed away from us.
In other words, from our perspective, Scholz’s star is fleeing the scene of a collision with us.
“Most stars this nearby show much larger tangential motion,” said Eric Mamajek, of the University of Rochester. “The small tangential motion and proximity initially indicated that the star was most likely either moving towards a future close encounter with the solar system, or it had ‘recently’ come close to the solar system and was moving away. Sure enough, the radial velocity measurements were consistent with it running away from the Sun’s vicinity — and we realized it must have had a close flyby in the past.”
...
Using data from the Southern African Large Telescope (SALT) and the Magellan telescope at Las Campanas Observatory in Chile, Mamajek and his collaborators were able to measure the star’s spectra and radial velocity. Through these observations they were able to deduce that Scholz’s star is a dim red dwarf approximately 20 light-years away. It is actually part of a binary system, with its partner being a small brown dwarf (or a ‘failed star’).
Taking these data, the researchers were able to model several different orbital possibilities and deduce that the star almost definitely (to a 98 percent certainty) came within 0.8 light years from the sun. Although this is still quite a margin, the star would have careened though the Oort Cloud — a hypothetical region filled with frozen cometary nuclei surrounding the solar system.

So how do you explain a galaxy being 25 MILLION Light Years away? Do you think that's not possible? We see it, which means what we are looking at happened 25 million years ago.
To not offend you, I'll refrain from commenting further....
Would have been interesting stuff from 70,000.
Whaddayamean 50,000 times?!? It’s only 49892.473118 times! ;’) Thanks U.
The Toba ‘supereruption’ is probably mythical. Regardless, even a small star passing less than a light year away wouldn’t trigger a volcanic eruption on Earth.
If indeed the Oort Cloud exists (so far it only exists as a mathematical consequence to the currently dominant related set of Solar System origin models) a bunch of those bodies would have wound up on screwy orbits, which could explain a bunch of the trans-Neptunian objects found in the last twenty years.

They killed our dinosaurs. D@mn you, Scholz!
Never mind.
I knew a member at my church years ago who worked at Caltech.
He demanded to know if I thought God was incapable of creating the light from distant stars on its way to earth and thus only give the appearance of immense age. Same thing with the geologic record on Earth, which evidences eons of time having passed
“Of course God can do that,” I told him. “But why would He?”
The fellow was non-plussed. The discussion had apparently never turned to that previously.
They did. It was Justin Bieber.
WISE 0720-0846 (full designation name WISE J072003.20-084651.2, also known as Scholz’s star after its discoverer)[3] is a binary system about 17–23 light-years (5.1–7.2 parsecs) from the Sun in the southern constellation Monoceros near the Galactic plane.[2] The primary is a red dwarf with a stellar classification of M9±1 and has 86±2 Jupiter masses.[2] The secondary is probably a T5 brown dwarf with 65±12 Jupiter masses.[2] The system has 0.15 solar masses.[2] The pair orbit at a distance of about 0.8 astronomical units (120,000,000 kilometers; 74,000,000 miles).[2] The system has an apparent magnitude of 18.3,[2] and is estimated to be 3–10 billion years old.[2]
It is estimated that the WISE 0720-0846 system passed about 52,000 astronomical units (0.25 parsecs; 0.82 light-years) from the Sun about 70,000 years ago.[2][3] Comets perturbed from the Oort cloud would require roughly 2 million years to get to the inner Solar System.[2] At closest approach the star would have had an apparent magnitude of about 10.3.[2] Such close approaches are expected to occur every 100,000 years or so.[2]
The star was first discovered to be a nearby star by astronomer Ralf-Dieter Scholz,[3] announced on arXiv in November 2013, and has been nicknamed Scholz’s star.

Relax. Your faith does not hinge on that which we cannot understand.
Was he stuned?
We are the balls on a pool table.....
Wow, and a global warming hoaxer as well.
There was something before light
There was something that communicated: “Let there be light”
John 1 says “In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it.”
John compares Christ to the first light that flashed into the beginning of the Universe
Science has yet to explain the Word (information) that directed the light
It’s not an “illusion.”Your preconceptions are wrong. It’s only an illusion if you think what you are looking at should be interpreted to mean what false science says it should.
I have met the fellow, professionally. On the topic of electric spacecraft thrusters (ion drives) and plasmas generally, he’s perfectly sane.
Just beware ... if you let the conversation drift off topic, it will fall over the edge in a hurry.
By my calculations, that is close enough to make a small child emit a very loud "Mom! He touched me!"
Recently I’ve been studying stars close to SOL and on approaching paths.
I didn’t think to look at stars which had recently passed.
Thanks for post
Science can’t explain God or anything else outside of nature. Only the infinite can truly contemplate infinity.
Our understanding is dwarfed by the tiniest part of creation, how would you propose to know the infinite? Revelation must suffice until we move beyond this mortal, finite body.
One atom’s gravity exerts an influence on the solar system and the Universe.
