I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#NASA announces new James Webb Space Telescope target launch date” NASA’s James Webb Space Telescope in the clean room at Northrop Grumman, Redondo Beach, California, in July 2020. Credit: NASA/Chris Gunn NASA now is targeting Oct. 31, 2021, for the launch of the agency’s James Webb Space Telescope from French Guiana, due to impacts from…
“#Runaway star might explain black hole’s disappearing act” This illustration shows a black hole surrounded by a disk of gas. In the left panel, a streak of debris falls toward the disk. In the right panel, the debris has dispersed some of the gas, causing the corona (the ball of white light above the black…
“#A population of asteroids of interstellar origin inhabits the Solar System” Discovery by Brazilian researcher reported in Royal Astronomical Society’s Monthly Notices provides clues for understanding the star nursery from which the Sun emerged.

“#In a first, astronomers watch a black hole’s corona disappear, then reappear” This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in purplish colors) gathers inward (left), becoming brighter, before shooting away from the black hole (middle and right). Astronomers…
“#New insights into the origins of our universe” A portion of a new picture of the oldest light in the universe taken by the Atacama Cosmology Telescope. This part covers a section of the sky 50 times the moon’s width, representing a region of space 20 billion light-years across. The light, emitted just 380,000 years…
“#How galaxies die: New insights into the quenching of star formation” A new theory explains how black holes grow as a function of galaxy mass and eventually quench star formation in their host galaxies. The images on this graph are of nearby galaxies at the present era taken by the Sloan Digital Sky Survey, chosen…
“#New transient X-ray source detected in the galaxy NGC 4945” Credit: CC0 Public Domain Using the Suzaku satellite, Japanese astronomers have detected a transient X-ray source in a nearby galaxy known as NGC 4945. The newly discovered source, designated Suzaku J1305−4930, appears to be a black hole binary. The finding is detailed in a paper…
“#Cases of black hole mistaken identity” Credit: X-ray: NASA/CXC/Penn State/B.Luo et al; Illustration: NASA/CXC/M. Weiss Astronomers have discovered one type of growing supermassive black hole masquerading as another, thanks to a suite of telescopes including NASA’s Chandra X-ray Observatory. The true identity of these black holes helps solve a long-running mystery in astrophysics. The misidentified…
“#Variability of blazar 3C 273 examined by astronomers” Spectra of 3C 273 at different activity states. The red spectrum corresponds to the date of the highest continuum flux observed, the blue spectrum corresponds to the lowest continuum flux observed, and the green spectrum corresponds to a medium point in continuum flux between the red and…
“#’Celestial sleuth’ sheds new light on Vermeer’s masterpiece ‘View of Delft’” View of Delft by Johannes Vermeer (1632-1675). Credit: Mauritshuis, The Hague Johannes Vermeer is one of the most celebrated artists of the 17th century’s Dutch Golden Age period. Widely known today for his “Girl with a Pearl Earring,” he was famed for his mastery…
