Selection of astronomical bodies and objects: Moon Mimas and Ida, an asteroid with its own moon, Dactyl; Comet Lovejoy and Jupiter, a giant gas planet; 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
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
The Webb images show tightly packed sheets, with filaments displaying structures on what NASA called "remarkably small scales," of about 400 astronomical units, or less than one-hundredth of a ...
An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. [1] In astronomy , the terms object and body are often used interchangeably.
The grapefruit-sized fragment crashed through the roof of a farm house, bounced off a large wooden console radio, and hit Hodges while she napped on a couch. [3] The 34-year-old woman was badly bruised on one side of her body, but was able to walk and able to take photos showing the fresh wound.
Sequence of HST images from 1994 to 2009, showing the collision of the expanding remnant with a ring of material ejected by the progenitor 20,000 years before the supernova [41] The three bright rings around SN 1987A that were visible after a few months in images by the Hubble Space Telescope are material from the stellar wind of the progenitor.
The Super Meteor 650 shares a resemblance to its younger counterpart, the Meteor 350, but with a more muscular appearance. It features a wide and low-slung seat, offering a relaxed riding position ideal for long-distance journeys. The cruiser aesthetics are enhanced by its teardrop-shaped fuel tank, scooped seat, and robust fenders. [6]
The 1933 [1] [3] [4] and 1946 [1] Draconids had zenithal hourly rates of thousands of meteors visible per hour, among the most impressive meteor storms of the 20th century. Rare outbursts in activity can occur when the Earth travels through a denser part of the cometary debris stream ; for example, in 1998, rates suddenly spiked [ 5 ] [ 6 ] but ...
