Astronomers have discovered a mysterious stream of ancient stars at the distant edges of the galaxy: a strange stellar breed so unlike any we’ve seen before, they may very well be the last of their kind.

This unusual collection of stars – called the ‘Phoenix stream’, after the Phoenix constellation in which they are visible – is what’s known as a stellar stream: an elongated chain of stars that used to exist in a spherical form, known as a globular cluster.

Such clusters can be torn asunder by a galaxy’s gravitational forces, in which case their globular form becomes warped, stretching out into a ghostly caravan of stars, fated to distantly orbit a faraway galactic core.

Tianwen-1, China’s first Mars probe, has smoothly flown more than 1.5 million kilometers away from Earth, leaving Earth’s gravitational field, and entering planned interplanetary orbit, the China National Space Administration (CNSA) said on Tuesday.

According to a press release the CNSA provided to the Global Times on Tuesday, the spacecraft is operating properly. Flight control and data communication is underway in an orderly and clear fashion.

We’re going back to Mars! NASA’s Perseverance Mars Rover will be launching soon for its seven-month journey to the Red Planet to search for signs of ancient life. And it’s bringing along a friend: a little helicopter named Ingenuity! Ingenuity will test the first powered flight on Mars.

“This is not just twice as difficult as any typical Mars mission; it’s twice squared — when you think about the complexity involved,” said Dr David Parker, the director of human and robotic exploration at the European Space Agency (Esa).

“And this satellite that Airbus will build — I like to call it ‘the first interplanetary cargo ship’, because that’s what it will be doing. It’s designed to carry cargo between Mars and Earth,” he told BBC News.

Dr Parker announced the European aerospace company’s role in the Earth Return Orbiter (ERO) at a NASA-Esa briefing with reporters just ahead of Thursday’s launch of the Perseverance robot.

Two Indian schoolgirls have discovered an asteroid which is slowly shifting its orbit and moving toward Earth.

Radhika Lakhani and Vaidehi Vekariya, both studying in 10th grade, were working on a school project when they discovered the asteroid, which they named HLV2514.

The girls, from the city of Surat in the western Indian state of Gujarat, were participating in a Space India and NASA project, which allows students to analyze images taken by a telescope positioned at the University of Hawaii.
