Supernova Physicsterm was first used by Fritz Zwicky (1898–1974) and Walter Baade (1893–1960), two pioneers of the photographic era. Zwicky himself was, by all accounts, a somewhat abrasive character who once stated that the other astronomers at the Mount Wilson Observatory were “spherical bastards.” When asked to e作者: Occipital-Lobe 時(shí)間: 2025-3-22 08:35 作者: 嚙齒動(dòng)物 時(shí)間: 2025-3-22 09:39
Supernovae in Our Neighborhoodernovae observed by human beings were ones within our own Milky Way Galaxy. This is hardly surprising as supernovae in external galaxies could not be discovered prior to the availability of powerful telescopes, and the true nature of them did not become apparent until the 20th century.

Supernovae as Visual Variable Starsther variable star. However, with even the brightest extragalactic supernovae in living memory being only 10th or 11th magnitude (excluding 1987A), the faint nature of these stars makes estimating their brightness a major challenge in all but the largest amateur telescopes.

Amateur Supernova Hunting in the 21st Century. He discovered two supernovae photographically using a 40-cm Newtonian reflector and later went on to become a professional astronomer.

Searching the Messier Galaxiess usually assumed to be identical to M 101. The Messier galaxies are bright, which is why they could be spotted with primitive 18th century telescopes. With the equipment now in many amateurs’ hands, they can easily be checked visually for supernovae. The majority of the Messier galaxies are best pl作者: 新字 時(shí)間: 2025-3-23 22:20

A supernova within a few hundred light-years of the earth would turn night into day as it would shine brighter than the full moon, but with all of the light radiating from a point source.作者: 罵人有污點(diǎn) 時(shí)間: 2025-3-25 10:03 作者: 工作 時(shí)間: 2025-3-25 12:43

Despite these obvious advantages, though, it is amazing just how faint an experienced visual observer, like the U.K.’s Gary Poyner, can go. With a 35-cm Schmidt-Cassegrain, he can just detect stars as faint as magnitude 16.8.作者: 橢圓 時(shí)間: 2025-3-25 17:34 作者: cartilage 時(shí)間: 2025-3-25 21:52 作者: 魅力 時(shí)間: 2025-3-26 00:26 作者: 整潔漂亮 時(shí)間: 2025-3-26 05:25
