An image made by the Hubble Space Telescope (bottom) is shown for comparison. According to a study by scientists at the University of California, Berkeley, between 1996 and 2006 the spot lost 15 percent of its diameter along its major axis. Xylar Asay-Davis, who was on the team that conducted the study, noted that the spot is not disappearing ...
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 ...
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.
Color code: red (0.4 – 0.6 keV), green (0.6 – 0.8 keV), blue (0.8 – 1.0 keV). Jupiter shows intense X-ray emission associated with auroras in its polar regions (Chandra observatory X-ray image on the left). The accompanying schematic illustrates how Jupiter's unusually frequent and spectacular auroral activity is produced.
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.
Lorimer Burst – Observation of the first detected fast radio burst as described by Lorimer in 2006. [1] [failed verification]In radio astronomy, a fast radio burst (FRB) is a transient radio pulse of length ranging from a fraction of a millisecond, for an ultra-fast radio burst, [2] [3] to 3 seconds, [4] caused by some high-energy astrophysical process not yet understood.
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 ...
In the widely accepted ΛCDM cosmological model, dark matter accounts for about 25.8% ± 1.1% of the mass and energy in the universe while about 69.2% ± 1.2% is dark energy, a mysterious form of energy responsible for the acceleration of the expansion of the universe. [17] Ordinary ('baryonic') matter therefore composes only 4.84% ± 0.1% of ...
