1]: 4 The actual weapon yield came very close to the design yield, which various sources have set at different values in the range of 1.4 to 1.45 Mt (5.9 to 6.1 PJ). The nuclear warhead detonated 13 minutes 41 seconds after liftoff of the Thor missile from Johnston Atoll. [5] Frame of the Starfish Prime Nuclear Test
2: Space Shuttle and other solid-fuel vehicles: Bruce Halker and Roy Westerfield lost their lives in the PEPCON disaster, an explosion of a factory that produced ammonium perchlorate for solid-fuel rocket boosters of the Space Shuttle and other launchers. 27 July 1989: Kennedy Space Center, US 1 Space Shuttle
A Type II supernova or SNII [1] (plural: supernovae) results from the rapid collapse and violent explosion of a massive star. A star must have at least eight times, but no more than 40 to 50 times, the mass of the Sun (M ☉) to undergo this type of explosion. [2]
Astronomers predict that the nova explosion could happen anytime between now and September. The last time this particular star system erupted was in 1946, Schaefer said, and another eruption will ...
In the case of a massive star's sudden implosion, the core of a massive star will undergo sudden collapse once it is unable to produce sufficient energy from fusion to counteract the star's own gravity, which must happen once the star begins fusing iron, but may happen during an earlier stage of metal fusion.
The Space Variable Objects Monitor is a small X-ray telescope satellite for studying the explosions of massive stars by analysing the resulting gamma-ray bursts, developed by China National Space Administration (CNSA), Chinese Academy of Sciences (CAS) and the French Space Agency , [45] launched on 22 June 2024 (07:00:00 UTC).
The next explosion is expected to occur from now through September. “The star system, normally magnitude +10, which is far too dim to see with the unaided eye, will jump to magnitude +2 during ...
Massive star explosions happen about three times per century in our galaxy. Others likely happened on the other side of the galaxy. Oak Ridge lab, UT scientists seek to better understand how ...
