Vũ trụ luôn là nơi chứa đựng vô vàn điều kỳ diệu và bí ẩn mà con người khát khao được tìm hiểu và chinh phục. Với sự phát triển vượt bậc của khoa học kỹ thuật, những hình ảnh chụp được từ kính thiên văn của Cơ quan Hàng không Vũ trụ Mỹ (NASA) đã phần nào giúp người xem hình dung vẻ đẹp của không gian vô tận ngoài Trái đất ấy.
TRUNGVU.NET – Dưới đây là một số hình ảnh ấn tượng được NASA chụp lại và minh họa lại, cho thấy vẻ đẹp và những điều thú vị về vũ trụ.
A unique type of exoplanet discovered with the Hubble Space Telescope. The planet is so close to its star that it completes an orbit in 10.5 hours. The planet is only 750,000 miles from the star, or 1/130th the distance between Earth and the Sun.
The circumbinary planet Kepler-16b – the first planet known to definitively orbit two stars. The cold planet, with its gaseous surface, is not thought to be habitable. The largest of the two stars, a K dwarf, is about 69 percent the mass of our sun, and the smallest, a red dwarf, is about 20 percent the sun’s mass. These star pairs are called eclipsing binaries.
Kepler-11, a sun-like star around which six planets orbit. At times, two or more planets pass in front of the star at once, as shown in a simultaneous transit of three planets.

A supermassive black hole with millions to billions times the mass of our sun. The accretion disk surrounding the center forms as the dust and gas in the galaxy falls onto the hole, attracted by its gravity. Also shown is an outflowing jet of energetic particles, believed to be powered by the black hole’s spin.

A galaxy known by its catalog name z8_GND_5296. Light from the galaxy took about 13.1 billion years to reach the orbiting Hubble Space Telescope and the Keck Observatory in Hawaii, both of which detected the galaxy in infrared light.
Kepler-22b, the most Earth-like planet ever discovered, is circling a star 600 light years away. It is the smallest and the best positioned to have liquid water on its surface – among the ingredients necessary for life on Earth.

A newly discovered planet, designated by the unglamorous identifier of OGLE-2005-BLG-390Lb, orbits a red star five times less massive than the Sun and located at a distance of about 20,000 light years.
Hydrocarbon ice forming on a liquid hydrocarbon sea of Saturn’s moon Titan. Some scientists suggest that clumps of methane-and-ethane-rich ice — shown here as the lighter-colored clusters — could float under some conditions.
