NGC 7635: туманность Пузырь NGC 7635: The Bubble Nebula

It's the bubble versus the cloud. NGC 7635, the Bubble Nebula, is being pushed out by the stellar wind of massive central star BD+602522. Next door, though, lives a giant molecular cloud, visible to the right. At this place in space, an irresistible force meets an immovable object in an interesting way.

Странный рассвет над Аргентиной A Strange Sunrise Over Argentina

Why would a rising Sun look so strange? No one is yet sure. What is clear is that the above unusual sunrise was captured last month from Buenos Aires, Argentina. The body of water in the foreground is Rio de La Plata, considered by many to be the widest river in the world.

Нобелевская премия за странную Вселенную Nobels for a Strange Universe

Thirteen years ago results were first presented indicating that most of the energy in our universe is not in stars or galaxies but is tied to space itself. In the language of cosmologists, a large cosmological constant is directly implied by new distant supernova observations.

Первый день МЕССЕНДЖЕРа MESSENGER s First Day

One solar day on a planet is the length of time from noon to noon. A solar day lasts 24 hours on planet Earth. On Mercury a solar day is about 176 Earth days long.

Круиз кометы Хартли 2 The Comet Hartley 2 Cruise

Early last November, small but active Comet Hartley 2 (103/P Hartley) became the fifth comet imaged close-up by a spacecraft from planet Earth. Still cruising through the solar system with a 6 year orbital period, Hartley 2 is is making astronomical headlines again, though.

M82: галактика со вспышкой звездообразования и сверхветром M82: Starburst Galaxy with a Superwind

Also known as the Cigar Galaxy for its elongated visual appearance, M82 is a starburst galaxy with a superwind. In fact, through ensuing supernova explosions and powerful winds from massive stars, the burst of star formation in M82 is driving the prodigous outflow of material.

Комета и корональный выброс массы на Солнце Comet and CME on the Sun

Did a sun-diving comet just cause a solar explosion? Probably not. This past weekend a comet dove toward the Sun and was followed very quickly by a Coronal Mass Ejection (CMEs) from the other side of the Sun.

QR-коды: не для человеческих глаз QR Codes: Not for Human Eyes

This communication was not meant for human eyes. It was not even meant for aliens eyes. It's an attempt to communicate directly with your smartphone. Cameras on many smartphones can image the above Quick Response (QR) code and then common applications can tell you what it means.

Распределение тёмной материи в симуляции "Большой" Dark Matter Movie from the Bolshoi Simulation

What if you could fly through the universe and see dark matter? While the technology for taking such a flight remains under development, the technology for visualizing such a flight has taken a grand leap forward with the completion of the Bolshoi Cosmological Simulation.

Тунгуска: крупнейшее столкновение последнего времени Tunguska: The Largest Recent Impact Event

Yes, but can your meteor do this? The most powerful natural explosion in recent Earth history occurred on 1908 June 30 when a meteor exploded above the Tunguska River in Siberia, Russia. Detonating with...
