A Small Satellite to Look for the Missing Matter from the Milky Way


A little satellite has embarked on researching the halo of the unbelievably hot gas encompassing the Milky Way, and it could enable researchers to find the gigantic amount of missing matter from the universe.

NASA sent the 26 lb satellite (that’s about 12 kilograms), called HaloSat, on the 13th of July from the International Space Station.

Researchers can’t locate the astounding 33% of all the matter that should exist in the universe. It’s not dark matter; it’s simply not there. They’ve computed how much matter was in the universe 400,000 years after the Big Bang in view of data encoded in the cosmic microwave foundation. What’s more, they’ve ascertained how much mass they see now in the cosmic systems, planets, stars, gas, and dust. In any case, the numbers don’t make any sense.

So, what’s the plan?

They ought to have all the matter today that they had back when the universe was 400,000 years of age, as said by Philip Kaaret, HaloSat’s central agent and an astronomer at the University of Iowa, in a declaration from NASA.

Researchers have made progress in finding lumps of the missing matter, and they’ve limited it down to two concealing spots: inside cosmic systems themselves, or spread out in the space between them. So researchers are beginning in the area that’s close to home, via hunting down the matter that is absent from the Milky Way.

HaloSat will endeavor to locate the missing matter by mapping the halo of the galaxy of superhot gas, which can get up to 3.6 million degrees Fahrenheit (or 2 million degrees Celsius), as indicated by NASA. That is sufficiently hot for oxygen gas to deliver X-rays, which HaloSat will gauge over the sky to make sense of the state of the halo and decide if it’s spread equitably around the Milky Way or in a smoothed disk, just like a fried egg.
