A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world.
This nebula is of particular interest to scientists because of its colors. Reflection nebulae glow because they are made up of extremely tiny particles of solid matter, up to 10 or even 100 times smaller than dust particles on Earth.
This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643 in the constellation of Lupus (the Wolf).
Guest “Let’s light this candle!” by David Middleton Moon safe for long-term human exploration, first surface radiation measurements show By Adam Mann Sep. 25, 2020 , 2:00 PM Moonwalkers take heart—China’s Chang’e 4 lander has made the first detailed measurements of the intense radiation that blasts the lunar surface and found that it’s safe for human…
Jupiter’s volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA’s Juno spacecraft. As with solar eclipses on the Earth, within the dark circle racing across Jupiter’s cloud tops one would witness a full solar eclipse as Io passes in front of the Sun.
This unbalanced the star and triggered runaway nuclear fusion that eventually led to an intensely violent supernova explosion. The supernova shone brightly for quite some time and was easily visible from Earth through even a small telescope until months later.
Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it.
Observations by NASA’s Hubble Space Telescope are showing that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse’s surface.
On Aug. 11, the mission will perform its “Matchpoint” rehearsal – the second practice run of the Touch-and-Go (TAG) sample collection event.
