Astronomers have detected a 'fast growing black hole'.

  Astronomers have found evidence of a rapidly growing black hole in the early universe, astronomers found in the Hubble Deep-Sky Survey, which existed only 750 million years after the Big Bang.  Astronomers have named this black hole GNz7q, the region in the sky where astronomers can study it well, and lurks like a "monster" in this region. Astronomers have labeled the GNz7q black hole as a "critical missing link" because it may help understand the connection between the first supermassive black hole and young galaxies.  The US space agency has also released an image of a supermassive black hole, taken by telescope, inside the dust-capped core of a vigorous star-forming "starburst" galaxy that, when this dust is removed, will  Eventually an extremely bright quasar will form. Quasars are thought to be the brightest objects in the universe, powered by black holes, and current theories predict that black holes begin their lives in dusty starburst galaxies be...

Samples from Enceladus could play a big role in the detection of life.

Saturn's satellite Enceladus, whose surface is covered by a thick layer of water ice, suggests evidence that Enceladus has a subsurface ocean, releasing mass of water, vapor and ice from its south pole into space.  In the picture above, we can see that high fountains of water and ice in the "Lion Stripes" area near the south pole of Enceladus. Cassini-Hoygens is a spacecraft, launched in 1997, and has been studying Saturn and its natural satellites since 2004. Studying data collected by the Cassini spacecraft from the subsurface ocean of Enceladus, the key elements for life in the ocean are the elements H, C, N, O and possibly S;  simple and complex organic compounds;  chemical disequilibrium at the water-rock interface;  Clement is temperature, pressure and pH, and this is the reason why Cassini's discovery makes the interior of Enceladus a prime location to find life other than Earth. Enceladus's low physical interaction with the inner Solar System makes it like...

Visible light helps to understand the Universe.

The Hubble telescope has used its five science instruments to help unravel the Universe; Hubble observes mainly in the ultraviolet and visible parts of the spectrum, but also has some near-infrared capabilities; Hubble observes any single object. in different wavelength bands, and each provides different information on the object under study. Researchers analyze the light collected by the Space Telescope to understand the Universe, the telescope collects the light, and with the help of this data from the Telescope, researchers can collect more information about specific celestial objects, because such celestial bodies  allow to develop better theories about the past, present and future and the universe in general. Researchers say that we humans' eyes also collect light, but they collect much less light than the space telescope, the part of the electromagnetic radiation that the human eye is sensitive to, is called visible light,  The human eye is able to see visible light beca...

The Solar Dynamics Observatory took image of mid-level solar flare emissions.

  March 31, 2022 at 2:35 p.m.: The Sun emitted a mid-level solar flare, an event imaged by NASA's Solar Dynamics Observatory, the Solar Dynamics Observatory that probes the Sun. Solar flares emanating from the Sun are powerful bursts of energy, which are a sudden increase in brightness at a location, that occurs when plasma is thrown out of the Sun's corona by a magnetic field. Solar flares and solar explosions can pose many risks to human equipment and humans. A solar flame is a large, luminous gas that extends outward from the surface of the Sun, also called a solar filament. Scientists still do not know the cause of solar flares, but scientists are researching how and why solar flares form.

The Mars Reconnaissance Orbiter once again saw the NASA Persevere rover and MarsHelicopter from space.

  Two images were taken of the surface of Mars by the Mars Reconnaissance Orbiter's HiRISE camera, Image A Perseverance Mars rover and Image B Ingenuity helicopter. The Mars Reconnaissance Orbiter, which was launched on 12 August 2005, and attained Mars orbit on 10 March 2006, is a multi-role spacecraft launched by NASA. The missions of the Mars Reconnaissance Orbiter are to study the geology and climate of Mars, while in orbit around Mars, and to provide reconnaissance of sites for future spacecraft landings, and to be collected by rover from the surface of Mars. done, sending the data back to Earth. The Perseverance Mars rover and Ingenuity helicopter were seen on the surface of Mars on 26 February 2022 by the Mars Reconnaissance Orbiter's HiRISE camera. The Perseverance Mars rover was seen sitting on the fractured base of the "Maze" formation prior to its drive to the delta of Jezero Crater, and about 656 feet (200 m) to the left saw the Ingenuity helicopter, wh...
