  2. Supernova - Wikipedia

    en.wikipedia.org/wiki/Supernova

    In the galaxy NGC 1365 a supernova (the bright dot slightly above the galactic center) rapidly brightens, then fades more slowly. [77] Supernova type codes, as summarised in the table above, are taxonomic: the type number is based on the light observed from the supernova, not necessarily its cause. For example, type Ia supernovae are produced ...

    This was noticed by the Hubble Space Telescope as a steady increase in luminosity 10,000 days after the event in the blue and red spectral bands. [37] X-ray lines 44 Ti observed by the INTEGRAL space X-ray telescope showed that the total mass of radioactive 44 Ti synthesized during the explosion was 3.1 ± 0.8 × 10 −4 M ☉ .

    en.wikipedia.org/wiki/2060_Chiron

    2060 Chiron is a ringed small Solar System body in the outer Solar System, orbiting the Sun between Saturn and Uranus.Discovered in 1977 by Charles Kowal, it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt.

  5. Phaeton (hypothetical planet) - Wikipedia

    en.wikipedia.org/wiki/Phaeton_(hypothetical_planet)

    Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) was the hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...

  6. Gravitational collapse - Wikipedia

    en.wikipedia.org/wiki/Gravitational_collapse

    The compression caused by the collapse raises the temperature until thermonuclear fusion occurs at the center of the star, at which point the collapse gradually comes to a halt as the outward thermal pressure balances the gravitational forces. The star then exists in a state of dynamic equilibrium. During the star's evolution a star might ...

  7. Sun - Wikipedia

    en.wikipedia.org/wiki/Sun

    The solar magnetic field extends well beyond the Sun itself. The electrically conducting solar wind plasma carries the Sun's magnetic field into space, forming what is called the interplanetary magnetic field. [86] In an approximation known as ideal magnetohydrodynamics, plasma particles only move along magnetic field lines. As a result, the ...

  8. NGC 4622 - Wikipedia

    en.wikipedia.org/wiki/NGC_4622

    On 25 May 2001, an image taken by the Hubble Space Telescope captured a supernova in NGC 4622, designated SN 2001jx (type unknown, mag. 17.5). [4] It was discovered by R. Buta and GG Byrd of the University of Alabama as well as T. Freeman of Bevill State Community College. [5] The type of supernova was not determined. [6]

  9. Crab Nebula - Wikipedia

    en.wikipedia.org/wiki/Crab_Nebula

    The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope.
