The Sun; Sirius A with Sirius B, a white dwarf; the Crab Nebula, a remnant supernova. A black hole (artist concept); Vela Pulsar, a rotating neutron star.
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f. As of 7 November 2024, there are 5,787 confirmed exoplanets in 4,320 planetary systems, with 969 systems having more than one planet. [1]
1ES 2344+514. Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371. 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib. S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
The Great Blue Hole, a giant submarine sinkhole, near Ambergris Caye, Belize. The following is a list of sinkholes, blue holes, dolines, crown holes, cenotes, and pit caves. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer.
This is a list of exceptional quasars for characteristics otherwise not separately listed. Quasar. Notes. Twin Quasar. Associated with a possible planet microlensing event in the gravitational lens galaxy that is doubling the Twin Quasar's image. QSR J1819+3845. Proved interstellar scintillation due to the interstellar medium. CTA-102.
In 2012, scientists exploring blue holes in the Bahamas discovered bacteria deep in the caves where no other life existed, potentially filling the knowledge “gap” on what types of lifeforms ...
List of planet types. From top to bottom: Mercury, Venus without its atmosphere, Earth and the Moon, Mars, Jupiter, Saturn, Uranus, and Neptune in false colour (not to scale) The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. The IAU defines that a planet in the Solar ...
