What has Hubble Space Telescope discovered?

Here are some of its major contributions to science: Helped pin down the age for the universe now known to be 13.8 billion years, roughly three times the age of Earth. Discovered two moons of Pluto, Nix and Hydra. Helped determine the rate at which the universe is expanding.

What did Hubble discover about the universe?

1373 Cincinnati

How much longer will Hubble operate in space?

The telescope completed 30 years in operation in April 2020 and could last until 2030–2040.

Is dark matter proven?

By some estimates, dark matter makes up about 85 percent of all the matter in the universe. “I once would have said the same things: it’s absolutely proven that there’s dark matter, don’t worry about it,” he said.

How did we find dark matter?

We can detect the dark matter through gravitational lensing, which detects shifts in light produced by distant celestial objects [5]. The bright spots outside the colored areas are stars and galaxies that are not part of the Bullet Cluster (Credit: X-ray: NASA/CXC/CfA/ M.

Will there be a dark matter Season 4?

Although SyFy canceled Dark Matter, there were still plenty of things audiences wanted to see on the show’s fourth season. You may consider it an underdog, but Dark Matter has developed some following during its run.

Why is space expanding?

The space between objects shrinks or grows as the various geodesics converge or diverge. Because this expansion is caused by relative changes in the distance-defining metric, this expansion (and the resultant movement apart of objects) is not restricted by the speed of light upper bound of special relativity.

Is space still expanding?

Over a century since Hubble’s first estimate for the rate of cosmic expansion, that number has been revised downwards time and time again. Today’s estimates put it at somewhere between 67 and 74km/s/Mpc (42-46 miles/s/Mpc).

How fast is space expanding?

This means that for every megaparsec — 3.3 million light years, or 3 billion trillion kilometers — from Earth, the universe is expanding an extra 73.3 ±2.5 kilometers per second.

Is space expanding faster than light?

But no object is actually moving through the Universe faster than the speed of light. The Universe is expanding, but the expansion doesn’t have a speed; it has a speed-per-unit-distance, which is equivalent to a frequency, or an inverse time.
