Image of collison between two Milky- way like Galaxies

Hubble Space Telescope has captured an image of collision between two Milky-Way like galaxies.

These two galaxies are known as NGC 2623 or Arp 243 are in the stages of emerging . The tail of NGC 2623 is richly populated with bright star clusters.

The galaxy NGC 2623 is an extensively studied galaxy and is bright in the infrared.

Images by Herschel's camera of our Milky way

Two Herschel's camera has taken images simultaneously of our Milky way which has never been seen before.

The image reveals a cold and turbulent region where material is just beginning to condense into new stars. It is located in the plane of our Milky Way Galaxy, 60 degrees from the center. Blue shows warmer material, red the coolest, while green represents intermediate temperatures.

Large areas of the Milky Way will be studied in a systematic way by Herschel , which will help astronomers to find the mysteries of star formation .

Details of our Milky Way

Enjoy the breath taking portrait of our Milky Way in detail.

The image spans the region of sky from the constellation of Sagittarius to Scorpius. The very bright and colourful feature towards the right of the image are the Rho Ophiuchi and Antares regions. Darker areas such as the Pipe and Snake nebulae also stand out.

The dusty lane of our Milky Way runs obliquely through the image, punctuated with bright, reddish nebulae including the Lagoon and the Trifid nebulae. A supermassive black hole is at the centre of our galaxy.

Motion of stars in distant galaxy

Astronomers have measured the motions of stars for the first time in a very distant galaxy, speeding around its host at twice the speed of our Sun through the Milky Way.

The speeding stars may help astronomers understand how such compact galaxies form so early in the Universe and then evolve into the galaxies we see in today's 13.7 billion year old Universe.

It will also help to see how these galaxies are formed with the help of Hubble's new Wide Field Camera 3.

Cosmic rays accelerated by exploded stars

Using ESO’s Very Large Telescope and NASA’s Chandra X-ray Observatory, astronomers have shown that cosmic rays from the Milky Way are very efficiently accelerated in the remnants of exploded stars.

Cosmic rays are extremely energetic particles – mostly protons – moving at close to the speed of light. They originate from outside our Solar System and are constantly bombarding the Earth’s atmosphere at a rate of some 100,000 per square metre per second.
