Восход Цветочной Луны Full Flower Moonrise

Rising as the Sun set, the Moon was bright and full in planet Earth skies on May 7 and known to some as a Flower Moon. Near the horizon it does seem to take on rose pink hues of reddened sunlight in this reflective twilight scene.

Длинный хвост кометы SWAN Long Tailed Comet SWAN

Blowing in the solar wind the spectacular ion tail of Comet SWAN (C/2020 F8) extends far across this 10 degree wide telephoto field of view. Captured on May 2 its greenish coma was about 6 light-minutes from Earth. The pretty background starfield lies near the border of the constellations Cetus and Aquarius.

Лунная аналемма Analemma of the Moon

An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day for one year. But the trick to imaging an analemma of the Moon is to wait bit longer.

LDN 1471: полость, выдутая звездным ветром LDN 1471: A Windblown Star Cavity

What is the cause of this unusual parabolic structure? This illuminated cavity, known as LDN 1471, was created by a newly forming star, seen as the bright source at the peak of the parabola.

Киль в перспективе Carina in Perspective

You need to be in the south, looking south, to see such a sky. And only then if you're lucky. Just above the picturesque tree is the impressive Carina Nebula, one of the few nebulas in the sky that is visible to the unaided eye.

Пролет около Земли аппарата "БепиКоломбо" Earth Flyby of BepiColombo

What it would look like to approach planet Earth? Such an event was recorded visually in great detail by ESA's and JAXA's robotic BepiColombo spacecraft last month as it swung back past Earth on its journey in to the planet Mercury.

Послание с Земли A Message from Earth

What are these Earthlings trying to tell us? The featured message was broadcast from Earth towards the globular star cluster M13 in 1974. During the dedication of the Arecibo Observatory - still one of the largest single radio telescopes in the world - a string of 1's and 0's representing the diagram was sent.

Радио, Большое Ухо и сигнал "Wow!" Radio, The Big Ear, and the WOW Signal

Since the early days of radio and television we have been freely broadcasting signals into space. For some time now, we have been listening too. A large radio telescope at Ohio State University known as affectionately The Big Ear was one of the first listeners.

Вид на M106 A View Toward M106

Big, bright, beautiful spiral, Messier 106 dominates this cosmic vista. The nearly two degree wide telescopic field of view looks toward the well-trained constellation Canes Venatici, near the handle of the Big Dipper. Also...

Островная вселенная Андромеды Andromeda Island Universe

The most distant object easily visible to the unaided eye is M31, the great Andromeda Galaxy some two and a half million light-years away. But without a telescope, even this immense spiral galaxy - spanning over 200,000 light years - appears as a faint, nebulous cloud in the constellation Andromeda.
