The entire Winter Galaxy “weighed carefully” for the first time ever – and it's 1.5TRION times the sun's mass

Our home galaxy – Milky Way – has been "carefully weighed" for the first time, and it is incredibly heavy.

The milk path can be seen from the earth on a clear night

Experts have tried to measure the weight of the milk The road for years, but it is a difficult job.

The main bond has been “dark matter”, which is hypothetical matter that science says we must exist – but there is no possibility to see it directly.

Therefore, earlier estimates of the weight of the Road Survey have not been outstanding – from 500billion to 3 trillion solar masses (the Sun’s mass).

“We just can’t detect dark matter directly,” says Laura Watkins, European Southern Observatory, who leads the team.

Measurement of the Milky Way has always proved difficult due to the significant amount of invisible “dark matter” lurking within [19659006] “That’s what leads to the current uncertainty in the Milky Way mass – you can’t measure exactly what you can’t see.”

But a revolutionary new weighing technique generates a total mass that takes into account the dark matter. It is practical because it constitutes about 90% of the Milky Way.

A single solar power mass weighs 2 x 10 to 30 kg, or 2,000,000,000,000,000,000,000,000,000,000,000 kilograms.

But the Milky Way weighs 1.5 trillion times the mass – that is about 3,000,000,000 billion billion billion billion.

Scientists were able to compile this astronomically high number by measuring the speed of global clusters – dense groups of stars revolving around the Milky Way’s spiral disk.

“The more massive galaxy, the faster moves its clusters under the weight of the hit,” says N. Wyn Evans, of the University of Cambridge.

“Most previous measurements have found the speed at which a cluster is approaching or returning from Earth , that is, the speed along our point of view.

“However, we could also measure the lateral movement of the gaps, from which the total velocity and, consequently, the galactic mass can be calculated

Scientists used years of data from NASA’s Hubble Space Telescope to make their measurements

By combining data from Nasa’s Hubble Space Telescope and ESA’s Gaia Space Observatory.

These data revealed how objects moved through the Milky Way

“Global clusters extend far away, so they are considered the best tracers astronomers use to measure the mass of our galaxy,” explained Tony Sohn, the Space Telescope Science Institute, who led the Hubble measurements .

And Roeland P. van der Marel, who also works at the Space Telescope Science Institute, added: “We were lucky to have such a good combination of data.”

“By combining Gaia’s measurements of 34 global clusters with measurements of 12 more remote clusters from Hubble, we could pin down the Milky Way mass in a way that would be impossible without these two space telescopes.”

Now that scientists know The road in the Milky Way, it will make it easier to make other precise cosmological measurements.

Deepest ever view of the miracle of space

Last year, scientists succeeded in successfully measuring all star light ever produced in the observable universe.

This includes not only current starlights, but all star light “produced in the history of observable history universe”, so it is quite large.

Our universe is likely to be about 13.7 billion years old and began forming stars within a few hundred million years.

The best guess of science is that there are about two trillion galaxies and trillion trillion stars.

Astrophysicist at Clemons College of Science used data from NASA’s Fermi Gamma-ray Space Telescope to see how many photons (light particles) have ever been on

Technically, the number is spoken as septenvigintillion – also know like this: 4,000,000,000,000 .000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.000.

Yes, it is how many photos make up all the star light ever produced in the observable universe, according to researchers writing in the journal Science.

In contrast, it is estimated that the number of grains of sand on the earth amounts to about 7.5 x 10 force 18 – or 7.500,000,000,000,000,000.

And the amount of water molecules on earth is estimated to be 4.6 x 10

A pair of asteroids the size of large buildings came uncomfortably close to Earth yesterday.

Last month, NASA released its best images of yet another potential day-asteroid called Bennu.
