Метеоры и болиды: свет и звук Meteor Fireballs in Light and Sound
15.03.2021

Yes, but have you ever heard a meteor? Usually, meteors are too far away to make any audible sound. However, a meteor will briefly create an ionization trail that can reflect a distant radio signal. If the geometry is right, you may momentarily hear -- through your radio -- a distant radio station even over static.


Северное сияние в форме флага над Швецией A Flag Shaped Aurora over Sweden
14.03.2021

It appeared, momentarily, like a 50-km tall banded flag. In mid-March of 2015, an energetic Coronal Mass Ejection directed toward a clear magnetic channel to Earth led to one of the more intense geomagnetic storms of recent years. A visual result was wide spread auroras being seen over many countries near Earth's magnetic poles.


SuperCam целится в Ма'аз SuperCam Target on Maaz
13.03.2021

What's the sound of one laser zapping? There's no need to consult a Zen master to find out, just listen to the first acoustic recording of laser shots on Mars. On Perseverance...


Мессье 81 Messier 81
12.03.2021

One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful Messier 81. Also known as NGC 3031 or Bode's galaxy for its 18th century discoverer, this grand spiral can be found toward the northern constellation of Ursa Major, the Great Bear.


Зодиакальный свет и Марс Zodiacal Light and Mars
11.03.2021

Just after sunset on March 7, a faint band of light still reaches above the western horizon in this serene, rural Illinois, night skyscape. Taken from an old farmstead, the luminous glow is zodiacal light, prominent in the west after sunset during planet Earth's northern hemisphere spring.


NGC 1499: туманность Калифорния NGC 1499: The California Nebula
10.03.2021

Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only about 1,000 light-years from the California Nebula.


Персеверанс: необычные камни и поиск жизни на Марсе Perseverance 360: Unusual Rocks and the Search for Life on Mars
9.03.2021

Is that a fossil?б Looking through recent images of Mars taken by the new Perseverance rover may seem a bit like treasure hunting, with the possibility of fame coming to the first person...


Три хвоста кометы NEOWISE Three Tails of Comet NEOWISE
8.03.2021

What created the unusual red tail in Comet NEOWISE? Sodium. A spectacular sight back in the summer of 2020, Comet NEOWISE, at times, displayed something more than just a surprisingly striated white dust tail and a pleasingly patchy blue ion tail.


Столбы туманности Орла в инфракрасном свете Pillars of the Eagle Nebula in Infrared
7.03.2021

Newborn stars are forming in the Eagle Nebula. Gravitationally contracting in pillars of dense gas and dust, the intense radiation of these newly-formed bright stars is causing surrounding material to boil away. This image...


Персеверанс поворачивает Perseverance Takes a Spin
6.03.2021

After arriving at Jezero Crater on Mars, Perseverance went for a spin on March 4. This sharp image from the car-sized rover's Navcam shows tracks left by its wheels in the martian soil. In preparation for operations on the surface of the Red Planet, its first drive lasted about 33 minutes.
