'Little green heart blood'

The water flowing out of the Ural Lake in Central Asia makes this lake look like a small green heart with blood. This is one of the most impressive universe images of the past week.

The bloody green heart in the picture is actually Aral Lake in Central Asia. Once the fourth largest lake in the world (not clear with the sea or any other water source), Lake Aral has been continuously shrinking for the past 50 years because its water has been used to irrigate fields. Photo: ESA.

This is not an image of an ultra-thin laptop, but a galaxy called NGC 4452. In this photo, taken by the Hubble space telescope, we can see the brightest point in the center of the galaxy. this. Photo: NASA.

The Southern European observatory captures the scene of two colliding galaxies causing stars and gas dust to strike. One of the two galaxies is called NGC 7252. Photo: ESO.

A stream of plasma (containing strong ionized material) escapes from the sun and "dances" two days before flying into space. NASA's Solar Dynamic Observatory captured this scene on October 28. A smaller plasma flow also appears in the frame. Photo: NASA.

NASA's Hubble Space Telescope captured the scene of a star named Merope sucking the cloud of gas and dust towards it. The giant cloud of dust and gas had approached Merope for the past 100 thousand years. By the time the cloud is swallowed by the star, its distance from the star is 3,500 times greater than the distance between the earth and the sun. Photo: AFP.

Two giant bubbles spewing gamma rays appearing in the middle of the Milky Way confounded astronomers because they did not know where they came from. Photo: NASA.
