Astronomers find strange ‘Manx’ comet that lacks a tail and may hold clues to Earth’s formation

Published

Astronomers have found a first-of-its-kind tailless comet whose composition may offer clues into long-standing questions about the solar system’s formation and evolution, according to research published on Friday in the journal Science Advances.

The so-called “Manx” comet, named after a breed of cats without tails, was made of rocky materials that are normally found near Earth. Most comets are made of ice and other frozen compounds and were formed in solar system’s frigid far reaches.

Researchers believe the newly found comet was formed in the same region as Earth, then booted to the solar system’s backyard like a gravitational slingshot as planets jostled for position.

Scientists involved in the discovery now seek to learn how many more Manx comets exist, which could help to resolve debate over exactly how and when the solar system settled into its current configuration.

“Depending how many we find, we will know whether the giant planets danced across the solar system when they were young, or if they grew up quietly without moving much,” paper co-author Olivier Hainaut, an astronomer with the European Southern Observatory in Germany, said in a statement.

The new comet, known as C/2014 S3, was discovered in 2014 by the Panoramic Survey Telescope and Rapid Response System, or Pan-STARRS. This network of telescopes scours the night-time skies for fast-moving comets, asteroids and other celestial bodies.

Typically comets coming in from the same region as the Manx grow bright tails as they approach the sun, the result of ice vaporizing off their bodies and gleaming in reflected sunlight.

But C/2014 S3 was dark and virtually tailless when it was spotted about twice as far away from the sun as Earth.

Later analysis showed that instead of ices typically found on comets, the Manx comet contained materials similar to the rocky asteroids located in a belt between Mars and Jupiter.

And C/2014 S3 appeared pristine, an indication that it had been in the solar system’s deep freeze for a long time, said University of Hawaii astronomer Karen Meech, the lead author.

The discovery of additional Manx comets could help scientists to refine computer models used to simulate the solar system’s formation, Meech said.

Fox News personality attacks women of color for ‘pouting’ over Trump’s racist tirades

Published

on

Fox News hosts at "The Five" responded to the press conference by four Congresswomen of color with outright sexism.

"Donald Trump won that press conference. Nancy and 'The Squad' lost. It looks like they want to victimize themselves even further," said host Jesse Waters, saying "We will not be silenced."

"I don’t think that’s the way to go against President Trump. You have to meet them on the same level," Waters continued, though he didn't explain what that meant. "They are continuing to play the victim and pout and now they want to impeach him for tweeting. They are saying he’s a white nationalist and he’s committing human rights violations and deporting all these people."

‘This is his plan to pit us against each other — to continue to enrich his friend’: Ilhan Omar demands Trump’s impeachment

Published

on

Rep. Ilhan Omar (D-MN) ripped President Donald Trump on Monday for his "blatantly racist" attacks on the four young women of color known as "The Squad."

Omar made her remarks in a press conference with Reps. Alexandria Ocasio-Cortez (D-NY), Ayanna Pressley (D-MA), and Rashida Tlaib (D-MI).

"This country was founded on the radical idea that we are created equal and endowed by our creator with inalienable rights. And, yes, we have a long way before we fully live up to those values. It is for this reason precisely that we have to take action when a president is openly violating the oath he took to the Constitution of the United States and the core values we aspire to," Omar said.

Trump tries to change the subject by blaming Obama — then accidentally admits he’s putting kids in ‘cages’

Published

on

President Donald Trump was the target of a Democratic press conference with four Congresswomen of color who were calling him out for racist tweets telling them to go back to their countries.

The women attacked every policy that Trump seems to be losing on. Trump seemed to try and pivot to another issue entirely, blaming former President Barack Obama for building the cages that he's putting children in after he takes them from their parents.

The Obama Administration built the Cages, not the Trump Administration! DEMOCRATS MUST GIVE US THE VOTES TO CHANGE BAD IMMIGRATION LAWS.
