Hercules A is one of the brightest giant galaxies in the cluster.

With the help of the Hubble telescope and the Very Large Array (VLA) radio telescope, researchers detected a spectacular jet driven by the gravitational energy of a supermassive black hole at the core of the elliptical galaxy Hercules A. In the center of the picture above, we can see how the yellow elliptical galaxy appears normal enough to be seen by Hubble's Hubble in visible wavelengths of light.

The elliptical galaxy is about two billion light-years away from our solar system, about 1,000 times more massive than the bulge of our Milky Way, discovery suggests it contains a 2.5-billion-solar-mass central black hole, Which is 1,000 times more massive than the black hole of our Galaxy. But there is an innocuous 3C 348 galaxy, long positioned in the Hercules constellation, known as the brightest radio-emitting object.

The radio wavelength of 3C 348 galaxy emits about a billion times more power than ours, making it one of the brightest extragalactic radio sources in the sky when viewed in the sky.

An invisible jet measuring one and a half million light-years wide that dwarfs the visible galaxy, the VLA reveals this invisible giant jet optically. A jet consists of a very high-energy plasma beam and subatomic particles, as well as a magnetic field at its center, which attracts gas and dust. The unusual ring structures seen in the outer part of both jets, the researchers say, suggest to us the history of explosions from the supermassive black hole at the center of the galaxy.

The innermost parts are not visible due to the excessive velocity of the material in the jet, the relativistic effect aligns all the light with the jet, and is confined to a narrow cone, so the light cannot be seen by us. Due to the distance from the galaxy, the jets become unstable, due to which their rings and blows break.

All radio sources of gas that are extremely hot, surrounded by clouds of X-ray emitters, cannot be seen in the optical-radio composite.

Hubble depicts an elliptical galaxy very close to the center of the optical-radio source, which once merged with the central galaxy. Hubble's data suggests that many other elliptical and spiral galaxies could be part of a group in the future, researchers say.

In the triple-star system, KOI-5Ab is seen orbiting the primary star...

KOI-5Ab continues to be a topic of discussion for researchers, as koi-5Ab has been seen orbiting the primary Star, confirming it has also been announced. koi-5ab revolves around the primary star, it was thought to be a planet half the size of Saturn in a planetary system, and was the only other planet candidate to be detected by the KOI-5Ab mission. Kepler mission operations were initiated by NASA in 2009, by the end of spacecraft operations in 2018, the Kepler spacecraft had discovered 2,394 exoplanets, or planets orbiting stars beyond our sun, and about 2,366 exoplanets such There are also those, which are still to be confirmed. David Ciardi, chief scientist at NASA's Exoplanet Science Institute, says the KOI-5AB was abandoned, because it was complicated, and we had thousands of candidates, and we were learning something new every day from Kepler, so that the KOI Mostly forgot to -5. KOI-5Ab is part of the Triple Star system, where KOI-5 is a group of three st...

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy. And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light. It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth. Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower. Today it is about 158 million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon. The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun. During those periods, to operate the space shut...

SpaceX is launching its next dragon spacecraft.

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket. SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space. Launch date: Sunday, July 21, 2019 at 7:35 pm International Space Station (ISS) us The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory. Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development. In addition, a series of payloads from identified private sector partners will be launched on this mission. More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX. One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists. ...
