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 ...
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
The supernova SN 2016gkg was detected by amateur astronomer Victor Buso from Rosario, Argentina, on 20 September 2016. [39] [40] It was the first time that the initial "shock breakout" from an optical supernova had been observed. [39] The progenitor star has been identified in Hubble Space Telescope images from before its
A meteor streaks through the night sky early Monday during the annual Perseid meteor shower behind St Mark's Tower, a 17th century coastal fortification near the village of Bahar ic-Caghaq, Malta.
[132] 2009 studies suggest an impact frequency of one every 50–350 years, for an object of 0.5–1 km in diameter; impacts with smaller objects would occur more frequently. Another study estimated that comets 0.3 km (0.19 mi) in diameter impact the planet once in approximately 500 years and those 1.6 km (0.99 mi) in diameter do so just once ...
It occurred approximately 51.4 kiloparsecs (168,000 light-years) [a] from Earth and was the closest observed supernova since Kepler's Supernova in 1604. Light and neutrinos from the explosion reached Earth on February 23, 1987, and it was designated "SN 1987A" as the first supernova discovered that year.
Stargazers had the best of both worlds over the weekend — and the photos are breathtaking. On Sunday, Aug. 11, the rare Perseid meteor shower reached its peak, while many stargazers also got a ...
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]
