The alien planet, a so-called “super-Earth,” is called 55 Cancri e and was discovered in 2004 around a nearby star in our Milky Way galaxy..

What is the hottest thing in the universe?

CERN’s Large Hadron Collider produced a temperature of over 5 trillion Kelvin in 2012 when they smashed together heavy ions traveling a fractionally below the speed of light. This is the hottest measured temperature that we know of.

What is the oldest neutron star?

HE 1523-0901 is the first star whose age was determined using the decay of the radioactive elements uranium and thorium in tandem with measurements of several neutron capture elements.

What galaxy contains the oldest stars?

What is the most powerful thing in the universe?

These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.

What color is the oldest star?

redAs stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star’s color can tell us something about that star’s age.

What is the youngest planet in the universe?

K2-33bThe planet K2-33b, discovered during the Kepler space telescope’s K2 mission, is the youngest fully formed exoplanet ever found. The Neptune-size planet is 5 million to 10 million years old. (For comparison, Earth is 4.5 billion years old.)
