The event occurred roughly 630 million years after the Big Bang, confirming that massive stellar births (and deaths) did indeed occur in the very early Universe. [30] When the burst occurred it was 3.3 billion ly away from our position, but due to the expansion of the universe and the movement of galaxies, the originating galaxy is now 30 ...
A well-known feature of Jupiter is the Great Red Spot, [103] a persistent anticyclonic storm located 22° south of the equator. It was first observed in 1831, [ 104 ] and possibly as early as 1665. [ 105 ] [ 106 ] Images by the Hubble Space Telescope have shown two more "red spots" adjacent to the Great Red Spot.
On April 10, 2020, the Juno spacecraft observed a fireball on Jupiter that was consistent with the impact of a 1–4-meter (3.3–13.1 ft) meteor. It was the first fireball to be detected by Juno . Researchers estimate Jupiter experiences approximately 24,000 impact events of this size per year—around 2.7 per hour.
Formally, c is a conversion factor for changing the unit of time to the unit of space. [4] This makes it the only speed which does not depend either on the motion of an observer or a source of light and / or gravity. Thus, the speed of "light" is also the speed of gravitational waves, and further the speed of any massless particle.
Astronomers have detected one of the most distant and energetic mysterious fast radio bursts in space, a millisecond-long blast of radio waves that traveled 8 billion years to reach Earth.
The burst was so bright that it blinded most gamma-ray instruments in space, preventing a true recording of its intensity. [ 10 ] [ 50 ] It was even detected by satellites not designed to detect gamma-ray bursts, such as Voyager 1 and a pair of Mars orbiters . [ 8 ]
Images taken of Jupiter by NASA's James Webb Space Telescope show a roaring jet stream over the gas giant's equator that is moving at speeds twice as fast as the winds of a Category 5 hurricane ...
Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67 × 10 −11 m 3 ⋅kg −1 ⋅s −2 [4])
