New Horizons reveals a 'snowman' at the edge of the solar system

New Horizons reveals a 'snowman' at the edge of the solar system

New results confirmed that the object rotates with a period of 15 hours or so, and is very dark, reflecting only 6 to 13 per cent of the incoming sunlight, Cathy Olkin, a planetary scientist at the Southwest Research Institute, said in a press conference.

"I'm here to tell you that last night, overnight, the United States spacecraft New Horizons conducted the farthest exploration in the history of humankind, and did so spectacularly".

"We have a healthy spacecraft", announced Alice Bowman, Mission Operations Manager for New Horizons, to a cheering crowd of scientists, engineers, members of the media, and guests on Tuesday morning.

"We think what we're looking at is perhaps the most primitive object that has yet been seen by any spacecraft, and may represent a class of objects which are the oldest and most primitive objects that can be seen anywhere in the present solar system", Mr Moore said.

The probe reached its target on New Year's Day at 12:33 am ET, though the signal travelling at light speed didn't reach Earth until yesterday morning.

By combining data from two different cameras on New Horizons, the Multispectral Visible Imaging Camera (MVIC), as well as LORRI, the team also produced a colour photo of MU69!

"Unfortunately the approach images we're showing you that came down first just aren't conducive to determining whether there are craters on the surface or not", said Mr.

And New Horizons' mission isn't over, Stern said. The left image is color-enhanced.

The team has nicknamed the larger lobe "Ultima" and the smaller lobe "Thule" - much the same way they gave unofficial names to the regions and features of Pluto and Charon before submitting the names for formal approval to the International Astronomical Union.

But now, clearer images have revealed a snowman.

The images we have of the object now show no obvious impact craters, but there are hills and ridges. "We are seeing a physical representation of the beginning of planetary formation, frozen in time", he said. Less than 1% of the data has returned so far.

Another round of imagery and data was received today and will be the focus of a news conference on Thursday.

The new image also resolved the debate about the nature of Ultima Thule.

Scientists had suspected that Ultima Thule would not be perfectly round since the summer of 2017, when a global network of observers found the rock passing in front of a distant star.

Better images will continue to come in over the following days and months.

The plutonium-powered probe should be capable of flying through the Kuiper Belt for another 10 years. Kuiper belt objects "are the first planetesimals", he said. The spacecraft captured it at 5:01 UTC on January 1, 2019, at a distance of just 28,000 kilometers.

The first detailed picture from Tuesday's flyby of the world reveals a double body shape - or snowman shape as scientists have called it.
