Galaxy & live fossil, mysterious space objects and rewriting human history




The Ashamed Shadow is moving forward, Hubble Space Telescope made an accidental discovery, and a mysterious object was found on the edge of the solar system – and only something that happened in space this week.

And then the cave that helps to rewrite human history and dinosaur fossil discovered in Antarctica.

Let's look at some of the incredible discoveries made behind Earth and beyond in recent days.

Rover is going to keep on rovin & # 39;

NASA has been astonished in his final autonomy on Vera Rubin Ridge, who has been home to Mars since September 2017. The drill samples and pictures of this location have given many scientists to study for the Mars and left crib between Gale Crater and Mount Sharp.

But no fear; the selfies will continue. Now, the trigger goes to the southern field of the crew that is full of clay ore. It's likely that those will be away from the ancient lakes on Mars that could have helped shape Mount Sharp lower levels.

This week, it was also revealed that scientists restart an Instrument on Violence to learn more about how Gale Crater and Mount Sharp were formed.

In the incredible news, the purposeful project team for the opportunity to rover on Mars sends new orders in the hope of waking up. As well known, Opportunity, or Oppy, has been disproportionate since a storm storm outside the planet took over in March in June. Good news: Oppy's team does not give up the battle again. Come along, Oppy!

Galaxy & living fossil & # 39; least

There is a sure sign that the Hubble Space Telescope is full of steam again as a perfect picture – and, of course, a discovery. The incredible telescope has been looking around the universe and reveals discoveries since 1990.

But the universe is not as rare as you could think. When Hubble looks around, he's like to look through a rich neighborhood where some objects prevent others from seeing them.

Hubble was taking an insight into the NGC 6752 world star cluster, which is 13,000 light years away at Halo Llaethog, when he saw a galaxy behind the full cluster. All in it, this galaxy ever seen is just hanging out in our back yard, about 30 million years light away.

Perhaps this is the most remote green galaxy ever. Not only is something wrong in the universe; That means that other galaxies are not cut or eaten.

Now, Serinists call it to Bedin 1. The small galax is only a fraction of our own size. It's almost as old as the universe, about 13 billion years, and because of its isolation, servers look like it as a "live fossil" from the beginning of the universe.

Meet Antarctica & # 39;

You probably did not expect dinosaurs to live in Antarctica. Not a climate friendly for reptiles. But it was not always so frosty and unhospitable. About 250 million years ago, it was totally cozy and covered with forests and rivers.

A new fossil discovered in Antarctica, whose name was "Antarctic king," was a comparison of the iguana dinosaurs of the so-called archaeologist that led to amphibians and bugs. This was a varied time for life, about 2 million years after the most known mass damage on Earth. After that, evolution appeared, and all types of species appeared.

"Antarctica had a combination of these new animals and stragglers of animals that had already disappeared in most places – which paleontologists who call dead poems have a walk. tomorrow's animals and animals yesterday, living in a cool place, "said Brandon Peecook, The lead study author and Field Museum researcher.

The sun and beyond

First, look at this incredible picture.

That's fine, here's a good friend Ultima Thule! Long time, do not see. But if you do not remember, that's the Kuiper Belt Bean far away about a billion miles past Pluto that NASA's New Horizons mission flies past New Year's Day.

And here is the most stringent we have to see. Expect colder images and new information about it soon.

Speaking of incredible trips, Solar Pro Parker completed its first orbit of the sun recently. The second orbit will start in April.

"We have always said that we do not know what to expect until we look at the data," said Projector Nour Raouafi. "The data we have had tips on many new things that we have not seen before and in possible new discoveries. Parker Solar Probe puts the mission of revealing the mystery of our Sun."

Cave of mystery

This is the only place in the world where the traces of some of the first people, of the name Denisovans, have been detected. And now we really learn more about the history of this cave.

A time line has now been set up for Denisova Cave, in the Altai Siberia Mountains, and is believed to have sheltered Neanderthalis and Denisovans at different times from around 300,000 to 50,000 years ago. The researchers believe that the Neanderthalians and Denisovans meet and have intervened 100,000 years ago, producing at least one child they know about.

New dating techniques, along with new fossils, helped make this timeline possible. But with a new search coming new questions, and the researchers will continue to look for more evidence. Until then, we know the Denisovans with just a handful of fragmented fossils.

What is that on the edge of the solar system?

It's not a stranger, but it's astonishing. And scientists are very excited to know something that has been predicted to exist for more than 70 years.

For the first time, a body has been found on the edge of the solar system that helps fill the space in the form of a planet. The size is key; Its radius is 1.3km (0.8 miles). That makes it a stepping step between dust and free bundles and fully formed planets.

The orbit behind Neptune is the Rejecting of Kuiper Belt, one of which is Pluto. These objects live in a cold, dark place, untreated by anything else, and act as records of the early solar system. But they're small, far and weak, which make them hard to see with telescopes. A new style of the ocultation name takes a large number of stars and looks for shadows of objects to pass, which made this discovery possible.

And now, researchers believe that this building block could be found to be only one of them.
