Что же произойдет, если Венера станет второй Землей? Рассмотрим первый вариант терраформирования, описанный в Википедии. Плюс, мы попробуем этов новой версии Universe Sandbox 2!
О Большом взрыве и взрывах сверхновых звезд рассказал д.ф.-м.н. Николай Чугай, зав. отделом нестационарных звезд и звездной спектроскопии Института астрономии РАН. Вселенная, какой мы видим ее сейчас, сформировалась в результате катастрофических взрывов разного масштаба. Прежде всего ее рождение — результат Большого Взрыва, который случился 14 миллиардов лет назад. Однако всё, что мы видим вокруг нас, — да и мы сами, — обязано своим возникновением взрывам сверхновых звёзд.

Universe Sandbox ² — игра про космос или симулятор, основанный на реальной физике симулятор космоса, который позволяет создавать, разрушать и взаимодействовать в невиданных ранее масштабах.
Он объединяет в реальном времени гравитацию, климат, столкновения и взаимодействия материи, чтобы показать вам красоту вселенной и хрупкость нашей планеты.
Universe Sandbox ² включает в себя версию для настольных компьютеров и режим VR с поддержкой HTC Vive, Oculus Rift Touch и Windows Mixed Reality.

Since its launch 25 Years ago, the Hubble Telescope has returned images of unprecedented beauty of a dynamic and changing universe.
In this episode of COSMIC JOURNEYS, Hubble’s most iconic images are bought to life to answer some of the most important questions facing astronomers today. Colliding galaxies, the birth and death of stars, jets of gas thrown out by material crashing into distant suns: these incredible images tech us valuable lessons about how galaxies are formed, what dark matter is and even the fate of the earth itself.
ABOUT US
Here at SpaceRip, we value the exploration of the unknown. We surpass boundaries for the sake of uncovering the mysteries of the cosmos and what they may tell us about our origin and our future. With our videos, we hope to educate our viewers on how we fit into the universe, and more so how we can do our part to better it.
We believe there is no better time to inform ourselves about the world around us. Our partnership with MagellanTV is aimed to educate viewers on our complex world to prepare for our rapidly changing future. Through our videos we hope to capture a variety of important topics with the overall goal of promoting positive discussion and action.
On February 23, 1987, vibrant light from a star that exploded about 166,000 years ago reached Earth from the Large Magellanic Cloud. Astronomers named it supernova 1987A. Observers in the southern hemisphere could see it with the naked eye.

Thirty years ago on February 24, 1987, observers in the southern hemisphere noticed a new object in the Large Magellanic Cloud. Today, we know this object as Supernova 1987A, and it was one of the brightest supernova seen in hundreds of years. Coupled with its relative proximity at about 160,000 light years from Earth, Supernova 1987A became one of the best opportunities ever for astronomers to study the phases before, during, and after the death of a star.
Since its discovery, telescopes around the world and in space have observed Supernova 1987A. This includes NASA’s Chandra X-ray Observatory, which has looked at this object repeatedly during its 17 years of science operations.
From 1999 until 2013, Chandra data showed an expanding ring of X-ray emission that had been steadily getting brighter. This was produced by the blast wave from the original explosion that had been bursting through and heating the ring of gas surrounding the supernova.
In the past few years, there have been striking changes in the Chandra data. This provides evidence that the explosion’s blast wave has moved beyond the ring into a region with less dense gas. This represents the end of an era for SN 1987A. Since astronomers do not know exactly lies beyond the ring, they will be watching carefully what happens next.
Over the next few thousand years, the expanding shell of hot gas will continue to glow in X rays. Eventually after rumbling across several thousand light years, the shell will disperse. By doing this, the supernova spreads the heavy elements created in the star and possibly triggers the formation of new stars from a cold interstellar cloud. Using data from Chandra and other telescopes, astronomers will continue to learn more about the details of this very important process that is responsible for life as we know it.
This time-lapse video sequence of Hubble Space Telescope images reveals dramatic changes in a ring of material around the exploded star Supernova 1987A.
The images, taken from 1994 to 2016, show the effects of a shock wave from the supernova blast smashing into the ring. The ring begins to brighten as the shock wave hits it. The ring is about one light-year across.
Discovered in 1987, Supernova 1987A is the closest observed supernova to Earth since 1604. The exploded star resides 163,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of our Milky Way.
