Voyager 1, NASA does not know where it is

In March of this year, 35 years have passed since the Voyager 1 spacecraft has been sent into space, leaving its mission to leave our solar system and explore interstellar space. That was the original premise, but NASA admits that it has no idea if it was successful.

The probe is the furthest, still acting object sent into space by man. The NASA-based Jet Propulsion Laboratory claims that Voyager 1 has gone to completely unknown territories, but the original mission team questioned this claim, saying that Voyager 1 is still within the Solar System. Since that time, the debate has been steadily increasing, and more and more scholars are starting to take part.

This week saw new findings from researchers at the University of Maryland and Boston University suggest that Voyager 1 entered the interstellar space on July 27, 2012. NASA confirms that there are many contradictory theories about the location of the probe, but she admits that she has no idea where she may be at the moment.

The space agency explains that the discrepancies in opinion come from the way scientists define the boundaries of our solar system. They claim that the boundary defines the magnetic field of the Sun and call it a “solar bubble”. The area beyond the magnetic field of our star is what scientists consider to be interstellar space, which has its own magnetic field.

Launched in 1977, the Voyager 1 probe monitors the magnetic field emitted by the Sun. The Jet Propulsion Laboratory counted that the probe passing through the solar bubble to the interstellar space would notice a distinct change in direction. Meanwhile, scientists say that the rotation of the solar system and interstellar space is in the same direction, so the transition may not be noticeable.

NASA will look for a twin of land

Kepler’s telescope, which has searched the cosmic sphere, has found many promising exoplanets in which conditions can be found for the development of life. Now NASA wants to gather some tools to find promising planets and plans to send a special satellite for this purpose.

The population of our planet is getting bigger, natural resources are closing at a rapid pace and in a while you will have to look for a new home where humanity can continue to grow. NASA using the Kepler telescope has been looking for such a home for several years and found some promising planets. The telescope can, however, explore only a particular segment of the cosmos, and for a broader search one needs something else.

NASA is working on a TESS (Transiting Exoplanet Survey Satellite) satellite that will search for life-changing planets. The device observes stars and searches for the shadows of planets orbiting on their background. Then he will calculate the size of the planet and the length of its orbit, so that the scientists will determine whether the object is suitable for habitation.

Astronomers have observed a giant supernova explosion

The gigantic and brightest of the stars so far detected, so-called. The supernova, detected an international team of astronomers – reported in his latest issue of the journal “Science”.

The explosion was so powerful that it would easily overwhelm the entire Milky Way galaxy in which the Solar System is located. A gigantic explosion occurred – according to preliminary estimates – in a galaxy 3.8 billion light years from Earth.

This extraordinary phenomenon was observed in the ASASSN (All-Sky Automated Survey for SuperNovae) program last year with a network of telescopes all over the Earth. According to “Science” this was “the most powerful supernova explosion ever observed throughout human history.”

The explosions of supernovae, massive and extremely massive stars torn by internal forces, which appear to be stronger than gravity trying to prevent them, are rarely observed.

The supernova explosion is usually 20 times brighter than the light emitted by the average spiral galaxy, which includes the Milky Way. Sometimes the explosion is 50 times brighter, which is 570 billion times brighter than our sun.

The last explosion that was named ASASSN-15lh was twice as strong as the previous record.

One of the astronomers participating in the project, Sobo Dong from Peking University, said he was so fascinated by the phenomenon that he “could not sleep all night”.

Another scientist, Benjamin Shappee of the Carnegie Institution for Science in Pasadena (California), described the outbreak as “surreal”. “This kind of discovery is the reason I’m an astronomer. Nature is very smart and sometimes has more imagination than we do, “he wrote in an e-mail.

Scientists agree that the explosion was so powerful and emitted so much energy that he questioned all of the current theories about supernovae. Nothing is known in particular about the mechanism of the phenomenon or the source of such an unimaginable amount of energy.

Scientists suspect that there may be similarly powerful stars in the universe that might explode at any moment. More detailed observations are planned, using the orbital Hubble telescope. According to Donga, the ASASSN-15lh explosion “can revise our approach to supernova phenomena.”
