The Carina Nebula was a classic target of the Hubble telescope - Webb's predecessor - although in this Webb version we get a very different rendering. Carina is one of the largest and brightest nebulae in the sky, located roughly 7,600 light-years from Earth. Nebulae are stellar nurseries. They are a massive clouds of gas and dust in which new stars are forming. Except in this Webb image, we not only see the stars - our eyes are drawn to all that gas and the dust. Astronomers refer here to a "cosmic reef", or "cosmic cliff" - a kind of broad demarcation between dust in the bottom half, and then gas in the top half. One of Webb's key scientific goals is to study how stars form, and Carina is an excellent place to do that.

The goal is to have the samples back on Earth in 2033.

The delivery will include some examples of igneous, or volcanic, rocks that Perseverance drilled out on the crater floor. These will tell the story, mostly, of Jezero before it was filled with lake water.

Critically, the samples are of a rock type that can be definitively dated. At present, ages on Mars can only be inferred indirectly.

The other part of the cache will include sedimentary type rocks that Perseverance has been collecting in recent months from the delta deposits in the western sector of the 45km-wide crater.

The eye is immediately drawn to the white nebula at centre-left where a relatively young - a few million years old - star called S1 is lighting up everything around it.

But look below at the red, bar-like feature that stretches across the entire image. This is an outflow of material from a protostar called VLA1623.

Rocks in the Australian Outback dating back 3.5 billion years may help scientists work out whether there has ever been life on Mars.

Researchers studying the Australian rocks say only ancient microbes could have shaped them the way they are.

Nasa's Perseverance rover should look for similarities when exploring rocks of a similar age on Mars, they say.

The wheeled robot is searching for evidence that biology took hold on the Red Planet early in its history.

They may not be the ones now being deposited at the location known as Three Forks, in Mars' Jezero Crater. Indeed, it's more likely to be the rocks Perseverance will be carrying at that time, when the robot might be driving way beyond the crater rim.

But scientists can't risk the prospect of the rover breaking down in the meantime with its rock collection stuck inside, and that's prompted them to build an insurance depot now.

Earth has taught us that life requires four essential inputs: liquid water, nutrients of some kind, an energy source, and time - an extended period of stability during which biology can get a foothold and establish itself.

We've long considered Mars to be the most likely candidate to host extra-terrestrial life, if not today then sometime in its distant past.

But for astrobiologists - scientists who study the possibility of life elsewhere in the Universe - the ice-covered moons of Jupiter and also Saturn are really starting to pique their interest.

Controllers commanded the robotic probe on Monday to fire its thrusters for 20 seconds.

This enabled Osiris-Rex to match Bennu's velocity through space, and bring it to about 20km from the rock at closest approach.

Heather Enos, the Osiris-Rex deputy principal investigator, was in the spacecraft manufacturer Lockheed Martin's control room in Littleton, Colorado, when completion of the thruster burn was confirmed.

"My heart-rate is three times faster than normal but I'm super-excited. Watching the team celebrate such an amazing milestone brings personal joy to me in so many ways I can't even explain," the University of Arizona, Tucson, researcher said.

The insight comes from the final measurements acquired by the American Cassini probe.

The satellite sent back its last data just before diving to destruction in the giant world's atmosphere in 2017.

"Previous estimates of the age of Saturn's rings required a lot of modelling and were far more uncertain. But we now have direct measurements that allows us to constrain the age very well," Luciano Iess from Sapienza University of Rome, Italy, told BBC News.

The professor's team has published an account of its work with Cassini in Science magazine.

The primary mission of DoT-1, launched in July, is to prove the performance of a new Core Data Handling System (Core-DHS). This avionics package is the brains of the satellite, consolidating among other equipment the main computer, GPS, the attitude and orbit control system, and the radio transmitter and receiver.

"We used to have all this in different trays and now it's all on the same board," said Rob Goddard.

"It's cut the mass down significantly. In future the Core-DHS will go in satellites that range in size from 20kg all the way up to 300-400kg. Obviously, in testing this core avionics we wanted to load it up with something as a payload and decided to go with this Raspberry Pi."

The Pi project was run in collaboration with the Surrey Space Centre at Surrey University.

Scientists want the fullest picture possible and the Athena X-ray telescope and the Lisa observatory give them that opportunity.

"The idea is that there is light and sound together," said Prof Günther Hasinger, Esa's director of science.

"With gravitational waves, we hear the shaking Universe; and the light comes from the matter falling into the black holes - 'the last cry of help' that is radiating in X-rays," he told BBC News.

A male African elephant named after fundraiser Stephen Sutton has been moved from West Midland Safari Park to a zoo.

The safari park, where Sutton was born, said he would learn bull elephant skills from two older male companions at Noah's Ark Zoo Farm near Bristol.

He would hopefully further support the survival of elephants, it added.

Stephen Sutton, from Staffordshire, raised £4.2m for the Teenage Cancer Trust before he died in 2014, aged 19.

A team of astronomers has found what it says is the best evidence yet for an elusive class of black hole.

They say the presumed "intermediate-mass" black hole betrayed its existence by tearing apart a wayward star that ventured too close.

These medium-sized objects are a long-sought "missing link" in the evolution of the cosmos.

Researchers used two X-ray observatories, along with the Hubble telescope, to identify the object.

"Intermediate-mass black holes are very elusive objects, and so it is critical to carefully consider and rule out alternative explanations for each candidate, said Dr Dacheng Lin, from the University of New Hampshire in Durham, US, who led the study.
