Мощный гамма-всплеск A Powerful Gamma Ray Burst
7.05.1998

Gamma-ray bursts are thought to be the most powerful explosions in the Universe, yet the cause of these high-energy flashes remains a mystery. Blindingly bright for space-based gamma-ray detectors the burst sources are so faint at visible wavelengths that large telescopes and sensitive cameras are required to search for them.



Спутник HETE-2 верхом на Пегасе HETE-2 Rides Pegasus
12.10.2000

The Stargazer, a modified Lockheed L-1011 aircraft, soared into the skies above Kwajalein Atoll in the pacific on October 9th. A small satellite observatory known as the High Energy Transient Explorer - 2 (HETE-2) was tucked into Stargazer's winged Pegasus rocket, slung beneath the large trimotor jet's fuselage.



Камера на борту "Свифта" Swift RocketCam
24.12.2004

A forward-facing RocketCam (TM) mounted inside the payload fairing of a Delta II rocket captured these dramatic video frames on November 20th -- as the Swift satellite observatory journeyed to an orbit 600 kilometers above planet Earth. Some frames were interpolated to correct for transmission problems.



Вспышки гамма-излучения Gamma Ray Burst: A Milestone Explosion
2.07.2000

Gamma-Ray Bursts (GRBs) were discovered by accident. Thirty three years ago today, satellites first recorded a GRB. The data plotted here show that the count rate of the satellite gamma-ray instrument abruptly jumped indicating a sudden flash of gamma-rays.



Сверхновая в NGC 2525 Supernova in NGC 2525
23.10.2020

Big, beautiful, barred spiral galaxy NGC 2525 lies 70 million light-years from the Milky Way. It shines in Earth's night sky within the boundaries of the southern constellation Puppis. About 60,000 light-years...



NGC 7814: Маленькое Сомбреро со сверхновой NGC 7814: Little Sombrero with Supernova
22.07.2021

Point your telescope toward the high flying constellation Pegasus and you can find this expanse of Milky Way stars and distant galaxies. NGC 7814 is centered in the pretty field of view that would almost be covered by a full moon.



WR 104: звёздная система в виде вертушки WR 104: A Pinwheel Star System
3.06.2014

Might this giant pinwheel one-day destroy us? Probably not, but investigation of the unusual star system Wolf-Rayet 104 has turned up an unexpected threat. The unusual pinwheel pattern has been found to be created by energetic winds of gas and dust that are expelled and intertwine as two massive stars orbit each other.



Взлет и падение сверхновой 2015F The Rise and Fall of Supernova 2015F
9.02.2016

Sit back and watch a star explode. The actual supernova occurred back when dinosaurs roamed the Earth, but images of the spectacular event began arriving last year. Supernova 2015F was discovered in nearby spiral...



Сверхновая сквозь пыль в галактике A Supernova through Galaxy Dust
23.02.2016

Telescopes around the world are tracking a bright supernova that occurred in a nearby dusty galaxy. The powerful stellar explosion was first noted earlier this month. The nearby galaxy is the photogenic Centaurus A, visible with binoculars and known for impressive filaments of light-absorbing dust that cross its center.



Звездное скопление, спиральная галактика, сверхновая Star Cluster, Spiral Galaxy, Supernova
25.05.2017

A cosmic snapshot from May 19, this colorful telescopic field of view spans about 1 degree or 2 full moons on the sky. Spiky in appearance, foreground Milky Way stars are scattered toward...
