What galaxy do we live in?
The Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way..
What is the oldest thing in the universe?
GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.
How old is the youngest galaxy?
Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.
What is the most dangerous thing in the universe?
Supermassive black holes are strange. The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.
Do galaxies die?
Galaxies die when the stars that live in them stop forming. Now, for the first time, astronomers have witnessed this phenomenon in a distant galaxy. Scientists were able to glimpse a galaxy as it ejected almost half of the gas it uses to form stars.
How old is space?
13.8 billion yearsUniverse is 13.8 billion years old, scientists confirm Scientists estimate the age of the universe by measuring its oldest light.
At what temperature will humans die?
44 °C (111.2 °F) or more – Almost certainly death will occur; however, people have been known to survive up to 46.5 °C (115.7 °F). 43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions and shock. Cardio-respiratory collapse will likely occur.
What’s the coldest thing on earth?
A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and volume has ever come to absolute zero.
What are the oldest objects in the Milky Way?
A new study has focused on the spectra of NGC 6652 obtained by the Cerro Tololo Observatory and found that the globular cluster NGC 6652.4. 05957 is 13.6 billion years old. This makes the cluster one of the oldest objects in the Milky Way.
What is hottest thing in the universe?
The dead star at the center of the Red Spider Nebula has a surface temperature of 250,000 degrees F, which is 25 times the temperature of the Sun’s surface. This white dwarf may, indeed, be the hottest object in the universe.
How old is the Milky Way 2020?
Astronomers have known that the Milky Way is among the oldest of galaxies. The new observations suggest it was indeed one of the first to get under construction. The study puts its age at 13.6 billion years, give or take 800 million years.
Is Lava The hottest thing on earth?
Lava is the hottest natural thing on Earth. It comes from the Earth’s mantle or crust. The layer closer to the surface is mostly liquid, spiking to an astounding 12,000 degrees and occasionally seeping out to create lava flows.
