"I spent an hour just staring at this image", lead researcher Pieter van Dokkum of Yale University says as he recalls first seeing the Hubble image of NGC 1052-DF2.
"This thing is astonishing: a enormous blob so sparse that you see the galaxies behind it. It is literally a see-through galaxy".
Closer monitorings utilizing the Hubble and also 10-meter Keck telescopes revealed that the item, now described NGC1052- DF2, belonged to a lately uncovered course of things called ultra-diffuse galaxies. Based on their observations, they found the mass to be what you'd expect to see from the stars alone, suggesting that the galaxy has no dark matter.
There's no good explanation for why and how this galaxy has no dark matter, Van Dokkum said.
Gemini then assisted by showing the galaxy was not interacting with other galaxies.
Donald Trump is going after Amazon and Jeff Bezos, again
And today Trump admitted in a tweet his concerns over the internet retail giant and its impact on traditional retail businesses. Kristi Noem, a South Dakota Republican, has called for legislation requiring online retailers to collect sales tax .
NASA specified that the galaxy has around one four hundredth of the expected amount of dark matter. It's so sparse that you see all of the galaxies behind it. One of the researchers stated that there is over five times the amount of dark matter in a galaxy than normal regular matter.
In other words, the question arises: if a galaxy did not start from dark matter, which then gravitationally attracted common matter, how did it form?
He also raised the possibility that another galaxy nearby was tweaking NGC 1052-DF2's motion through an element of MOND called the "external field effect". "The standard paradigm has gas falling into halos - or lumps - of dark matter and turning into stars to make a galaxy", he said.
"Dark matter is apparently not a requirement for forming a galaxy", said Van Dokkum.
The galaxy is located 63 million light-years away from our Milky Way. The galaxy is a complete mystery, as everything about it is unusual.
Dark matter does not emit electromagnetic radiation, and remains immune to direct observation.
Dark matter is believed to exist because of its gravitational effects on visible matter in the cosmos. One idea is that the gas got concentrated as it was being ejected from a galaxy merger; another is that it formed from matter spewed out by quasars. The team plans to publish another research paper looking at the bright star clusters that could shed more light on the mystery of NGC1052-DF2. It turns out that a galaxy without dark matter is incompatible with models that replace it using modified gravity. Three of them appear similar to NGC 1052-DF2. Imaging them enabled the research study group to establish their activities orbiting the galaxy, which could, consequently, give an action of the quantity of mass that is associated with maintaining the things in position.
Finding a total lack of dark matter might also, paradoxically, give scientists evidence for the existence of the odd stuff. Scientists have found that normal matter - the stuff we do see - makes up only around 15 per cent of all the matter in the universe.
It's there but it's not going to help, first of all Chelsea and then us... "But, for us, three points for us will be fantastic". Harry Winks will miss the game with an ankle injury, but Toby Alderweireld is hoping to make his return.

However, the state's falling unemployment rate hasn't translated to better performance in job growth compared to other states. Virginia's unemployment rate continues to be below the national rate, which was unchanged again in February at 4.1 percent.
