This Just In:First Interstellar Meteor Confirmed

According to The Harvard Gazette,two scientests with the Harvard University Department of Astronomy,Dr.Amir Siraj and Dr.Harvey Loeb,wrote a paper called "Discovery of a meteor of interstellar origin."The paper described the meteor as originating from an unbound hyperbolic orbit,or interstellar space.This meteor was discovered when Dr.Siraj,at the suggestion of Dr.Loeb,went combing through NASA's Center for Near Earth Object Studies (CINEOS) and found CINEOS 2014-01-08,a meteor that measured only 1.5 ft/.457 m across.It was traveling an estimated 45 kilometers per second/100,662.1 mph and ignited into a fireball off the coast of Papua,New Guinea on 8 JAN 2014.This was three years earlier than interstellar object Oumuamua.Comet 21/Borisov was discovered by Crimean amateur astronomer and telescope maker Gennadiy Borisov on 29 AUG 2019.*Dr.Siraj said:But what was unusual about this meteor was that this object had a very high impact speed and the unusual direction at which it encountered our planet.Anything traveling that fast is too fast to be captured by the Sun's gravity.It must have been ejected by a neigbouring star and sent our way if it was traveling with such velocity.*On 1 March 2022,LTGEN John E. Shaw,Deputy Commander U.S. Space Force,sent a memorandum to NASA Science Mission Directorate,then under Dr.Thomas Zurbuchen.Dr.Joel Mozer,chief scientest of Space Operations Command,the U.S. Space Force service element of U.S. Space Command,reviewed analysis of additional data available to the Department of Defense related to the finding.Dr.Mozer confirmed that that the velocity estimate reported to NASA was sufficiently accurate to indicate an interstellar trajectory.

🌎 LIVE Oumuamua Interstellar Object ☄️ NASA's Eyes - WorldCam

As of 2024,only two interstellar objects have been discovered:Oumuamua in 2017 and Comet 21/Borisov in 2019.Some say Oumuamua is an asteroid,while others say it is a comet.Arizona State University School of Earth and Space Exploration suggests it is a chunk of a Pluto-like planet.Oumuamua is headed out of the Milky Way forever.In four years,it will pass Neptune's orbit on its way back to interstellar space.

🌎 LIVE Oumuamua Interstellar Object | NASA's Eyes

The first known Interstellar Object,Oumuamua,was discovered on 19 October 2017 by Robert Weryk using the Pan-STARRS 1 telescope at Haleakala Observatory,Hawaai.Reddish in color,it is possibly a hyperbolic asteroid,though others have proposed it is a comet.It's classification is still a mystery.It is headed back out to interstellar space.In 2019,Interstellar Comet Borisov/21 was the second interstellar object discovered.You will note in the animation a track out to 90377 Sedna,a reddish dwarf planet beyond the orbit of Neptune.Spectroscopy has shown its surface to be mostly a mixture of solid ices of water,methane and oxygen,along with widespread deposits of reddish-colored tholins,a chemical make-up similar to other trans-Neptunian objects.Perhaps tholins are also giving Oumuamua its reddish color.
