Is there a diamond planet?
Move over, Hope Diamond.
The most famous gems on Earth have new competition in the form of a planet made largely of diamond, astronomers say.
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?
Milky Way’sAstronomers Find Fossils of Early Universe Stuffed in Milky Way’s Bulge. New research shows that star cluster HP1 (seen here through Chile’s Gemini South telescope) may contain some of the oldest stars in the Milky Way, dating to roughly 12.8 billion years old.
Will you age faster on Mars?
To a watcher on Earth, yes. To a very, very, very, very, very minute degree time will move more slowly for you on Mars, as compared to Earth, due to gravitational time dilation. … In their reference frame on Earth, they are aging at exactly the same rate. They will always age at the same rate.
What is the hottest star color?
blue starsThe hotter the star, the further up the spectrum you go. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes.
What color are the coldest stars?

What is the smallest thing in the universe?
An atom is the smallest unit of any element in the periodic table. … Experiments found that each atom has a tiny, dense nucleus, surrounded by a cloud of even tinier electrons. The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe.
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.)
What is the oldest thing in the universe?
Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.
