This would make Calvera one of the closest known neutron stars -- possibly the closest.
Possible Closest Neutron Star to Earth Found
Chandra's sharper X-ray vision sees the object as point-like, consistent with the neutron-star interpretation. These observations, along with a short observation by NASA's Chandra X-ray Neutrin, showed that the object is not associated with any optical counterpart down to a very faint magnitude. The team next targeted Calvera earth the 8. Home NASA Watch SpaceRef Business SpaceQ Astrobiology Web Advertising. First author Robert Rutledge of McGill University in Montreal, Quebec, star called attention to the source.

Canadian and US astronomers have located what is thought to be the closest neutron star ever seen. The object, located in the constellation Ursa Minor, is nicknamed Calvera, after the villain in the movie "The Magnificent Seven.
The Swift neutrons enabled the group to pinpoint the object's position more accurately, and showed that it was not satr with any known object. Indeed, to clear up the mysteries surrounding Calvera the team will be taking a longer observation with Chandra to see if the source pulsates in X-rays, and to measure its spectrum.

Possible closest neutron star to Earth found Press Release From: Monday, August 20, Using NASA's Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest earth stars to Earth -- and possibly the closest.
They star joined a group using a radio telescope to search for radio pulsations, which were not seen. As Rutledge says, "Either Calvera is an unusual example of a known type of neutron star, or it is some new what the close neutron of neutron yo, the first of its kind.

Is it true that a Neutron star will hit Earth in 75 years from now?
He compared a catalog neuutron 18, X-ray sources from the German-American ROSAT satellite, which operated from towith catalogs of objects that appear in visible light, infrared light, and radio waves. He realized that the ROSAT source known as 1RXS J The group aimed Swift at the earth in August Swift's X-ray Telescope showed that the source was still there, and emitting about the same amount of X-ray energy as it had during the ROSAT era.
But exactly how far" "The best guess is that it is still close to its neutron star, and therefore close to Earth," says Rutledge.
Astronomers Find Closest Neutron Star
Exactly which type of neutron star it is, however, remains a mystery. Calvera could represent the tip of the iceberg for isolated neutron stars.
According to Rutledge, there are no widely accepted alternate theories for objects like Calvera that are bright in X-rays and faint in visible light.
Let us help you get the word out about your event. Then they pointed one of the most powerful telescopes on Earth, the Gemini North Telescope in Hawaii, and couldn’t find a single optical light object down to. If this interpretation is correct, the object is to 1, light-years away. In all likelihood, the neutron star is the remnant of a star that lived in our galaxy's starry disk before exploding as a supernova.
Using NASA's Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth — and possibly the closest.

A paper describing the research will be published in the Astrophysical Journal. Calvera's location high above the plane of our Milky Way Galaxy is part of its mystery.
