A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. The event, which could occur anytime between now and September, is creating a buzz within ...
T Coronae Borealis, also known as the "Blaze Star," is actually a pair of stars located 3,000 light-years away. The star system is a recurring nova, with Earth-visible explosions every 79 to 80 ...
NASA has predicted that a "once-in-a-life-time" star explosion -- or nova -- will be visible to the naked eye sometime this summer.
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
GRB 221009A came from the constellation of Sagitta and occurred an estimated 1.9 billion years ago, [14] however its source is now 2.4 billion light-years away from Earth due to the expansion of the universe during the time-of-flight to Earth. [15]
This supernova event was observed in a galaxy about 238 million light years (73 megaparsecs) from Earth. The theoretical basis for pair-instability collapse has been known for many decades [13] and was suggested as a dominant source of higher mass elements in the early universe as super-massive population III stars exploded.
The stellar eruption will take place in a system called T Coronae Borealis, which is 3,000 light-years away from Earth. It contains two stars: a dead star, also known as a “ white dwarf ...
The stars in the orbiting pair are close enough to each other that they interact violently. The red giant becomes increasingly unstable over time as it heats up, casting off its outer layers that ...
