Персеверанс: селфи с Индженьюити Perseverance Selfie with Ingenuity

On sol 46 (April 6, 2021) the Perseverance rover held out a robotic arm to take its first selfie on Mars. The WATSON camera at the end of the arm was designed to take close-ups of martian rocks and surface details though, and not a quick snap shot of friends and smiling faces.

Формирование первых звезд: моделирование Simulation: Formation of the First Stars

How did the first stars form? To help find out, the SPHINX computer simulation of star formation in the very early universe was created, some results of which are shown in the featured video. Time since the Big Bang is shown in millions of years on the upper left.

Туманность Ориона: вид в телескоп имени Хаббла Orion Nebula: The Hubble View

Few cosmic vistas excite the imagination like the Orion Nebula. Also known as M42, the nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-years away.

Солнечное затмение и бумажная Луна A Paper Moon Solar Eclipse

It may look like a paper Moon. Sailing past a canvas Sun. But those are not cardboard clouds. And it's not make believe.б The featured picture of an orange colored sky is real -- a digital composite of two exposures of the solar eclipse that occurred earlier this month.

Танцующие полярные сияния на Сатурне The Dancing Auroras of Saturn

What drives auroras on Saturn? To help find out, scientists have sorted through hundreds of infrared images of Saturn taken by the Cassini spacecraft for other purposes, trying to find enough aurora images to correlate changes and make movies.

Пиксели на Солнце Pixels in the Sun

These two panels, composed of video frames made with a safe solar telescope and hydrogen alpha filter, show remarkably sharp details on the solar disk and giant prominences along the Sun's edge on June 6 (top) and June 18.

Андромеда на одном снимке Andromeda in a Single Shot

How far can you see? The Andromeda Galaxy, 2.5 million light years away, is the most distant object easily seen by the unaided eye. Other denizens of the night sky, like stars, clusters, and nebulae, are typically hundreds to thousands of light-years distant.

Мессье 99 Messier 99

Grand design spiral galaxy Messier 99 looks majestic on a truly cosmic scale. This recently processed full galaxy portrait stretches over 70,000 light-years across M99. The sharp view is a combination of ultraviolet, visible, and infrared image data from the Hubble Space Telescope.

STARFORGE: моделирование звездообразования STARFORGE: A Star Formation Simulation

How do stars form? Most form in giant molecular clouds located in the central disk of a galaxy. The process is started, influenced, and limited by the stellar winds, jets, high energy starlight, and supernova explosions of previously existing stars.

HD 163296: джет от формирующейся звезды HD 163296: Jet from a Star in Formation

How are jets created during star formation? No one is sure, although recent images of the young star system HD 163296 are quite illuminating. The central star in the featured image is still forming but seen already surrounded by a rotating disk and an outward moving jet.
