I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Ground system for NASA’s Roman Space Telescope completes major review” High-resolution illustration of the Roman spacecraft against a starry background. Credit: NASA’s Goddard Space Flight Center When it launches in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope will create enormous panoramic pictures of space in unprecedented detail. The mission’s wide field of view will…
“#Image: Hubble snaps ghostly galaxy” Credit: ESA/Hubble & NASA, M. Gregg A notable feature of most spiral galaxies is the multitude of arching spiral arms that seemingly spin out from the galaxy’s center. In this image, taken with the NASA/ESA Hubble Space Telescope, the stunning silvery-blue spiral arms of the galaxy NGC 4848 are observed in immense detail….
“#NASA mission will study the cosmos with a stratospheric balloon” This illustration shows a high-altitude balloon ascending into the upper atmosphere. When fully inflated, these balloons are 400 feet (150 meters) wide, or about the size of a football stadium, and reach an altitude of 130,000 feet (24.6 miles or 40 kilometers).

“#Hubble Space Telescope captures summertime on Saturn” NASA’s Hubble Space Telescope captured this image of Saturn on July 4, 2020. Two of Saturn’s icy moons are clearly visible in this exposure: Mimas at right, and Enceladus at bottom. This image is taken as part of the Outer Planets Atmospheres Legacy (OPAL) project. OPAL is helping…
“#Spectacular UV flash may explain how white dwarfs explode” Blue dot indicates the location of SN2019yvq in a relatively nearby galaxy 140 million light-years from Earth. Credit: Northwestern University For only the second time ever, astrophysicists have spotted a spectacular flash of ultraviolet (UV) light accompanying a white dwarf explosion. An extremely rare type of…
“#Dark energy: map gives clue about what it is – but deepens dispute about the cosmic expansion rate” This image of the NGC 1398 galaxy, which is located in the Fornax cluster, was taken with the Dark Energy Camera.

“#Study illuminates fates of distant planetary atmospheres” An artist’s rendering of L98-59b, a planet spotted in another star system which may have an atmosphere. Two scientists simulated thousands of such planets to better understand how atmospheres form.

“#First image of a multi-planet system around a sun-like star” The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more…
“#New cosmic magnetic field structures discovered in galaxy NGC 4217” The spiral galaxy NGC 4217 has a huge magnetic field that is shown here as green lines. The data for this visualization were recorded with the radio telescope Karl G. Jansky Very Large Array (VLA) of the National Science Foundation. The image of the galaxy…
“#’Lost’ world’s rediscovery is step toward finding habitable planets” Credit: Pixabay/CC0 Public Domain The rediscovery of a lost planet could pave the way for the detection of a world within the habitable “Goldilocks zone” in a distant solar system. The planet, the size and mass of Saturn with an orbit of thirty-five days, is among…
