Петля в Лебеде Cygnus Loop Supernova Shockwave
18.07.1995

15,000 years ago a star in the constellation of Cygnus exploded. This picture shows a portion of a shockwave from this supernova explosion still expanding past nearby stars. The collision of this gaseous...



Шер 25: ожидающаяся сверхновая? Sher 25: A Pending Supernova?
12.08.1997

No supernova has ever been predicted - yet. These dramatic stellar explosions that destroy stars, that create and disperse the elements that compose people and planets, that light up the night sky, are not so well understood that astronomers can accurately predict when a star will explode - yet. Perhaps Sher 25 will be the first.



Тарантул и сверхновая звезда The Tarantula and the Supernova
27.10.1995

In this close-up of the Large Magellanic Cloud, the spidery looking nebula on the left is fittingly known as as the Tarantula nebula. It is an emission nebula surrounding a cluster of hot, young stars called the 30 Doradus super cluster.



Далекая судьба A Distant Destiny
14.01.1998

Watching galaxies recede, observational astronomers of the 20th century discovered an astounding fact - the Universe is expanding. Will it continue to expand forever? The speed of light is finite so looking into the distant Universe is equivalent to looking at the distant past.



Звездные войны в NGC 664 Star Wars in NGC 664
18.04.1998

Long ago in a galaxy far, far away, locked in their final desperate struggle against the force of gravity ... two stars exploded! stellar explosions - Supernovae - are among the most powerful events in the Universe, estimated to release an equivalent energy of up to 1 million trillion trillion (1 followed by 30 zeros) megatons of TNT.



Спиральная галактика NGC 3370: вид в телескоп Хаббла Spiral Galaxy NGC 3370 from Hubble
12.10.2008

Is this what our own Milky Way Galaxy looks like from far away? Similar in size and grand design to our home Galaxy (although without the central bar), spiral galaxy NGC 3370 lies about 100 million light-years away toward the constellation of the Lion (Leo).



Близкая сверхновая в спиральной галактике M100 A Nearby Supernova in Spiral Galaxy M100
7.03.2006

One of the nearer supernovas of recent years was discovered last month in the bright nearby galaxy M100. The supernova, dubbed SN 2006X, is still near its maximum brightness and visible with a telescope...



Остаток сверхновой в Туманности в Парусах The Gum Nebula Supernova Remnant
7.11.2000

Because the Gum Nebula is the closest supernova remnant, it is actually hard to see. Spanning 40 degrees across the sky, the nebula is so large and faint it is easily lost in the din of a bright and complex background.



Остаток вспышки сверхновой: кулинария в Большом Магеллановом Облаке Supernova Remnant: Cooking Elements In The LMC
9.05.1996

Massive stars cook elements in their cores through nuclear fusion. Starting with the light elements of hydrogen and helium, their central temperatures and pressures produce progressively heavier elements, carbon, oxygen, nitrogen, etc. up through iron.



Остаток сверхновой SN 1006 SN 1006 Supernova Remnant
4.07.2008

A new star, likely the brightest supernova in recorded human history, lit up planet Earth's sky in the year 1006 AD. The expanding debris cloud from the stellar explosion, found in the southerly constellation of Lupus, still puts on a cosmic light show across the electromagnetic spectrum.
