Oldest known superluminous supernova discovered
... as they did with type 1a supernovae. Type 1a supernovae are exploding white dwarf stars and are used in cosmology as typical "standard candles" for measuring the expansion of the Universe. Since SLSN can be anywhere from 50 to 100...

Astronomers find stars forming just 250 million years after Big Bang
... that followed after the Big Bang. “Determining when cosmic dawn occurred is akin to the Holy Grail of cosmology and galaxy formation. With these new observations of MACS1149-JD1 we are getting closer to directly witnessing the...

New measurement deepens mystery of Universe’s expansion rate
... it popped into existence over 13 billion years ago. His observation led to the creation of the Hubble Constant; a cosmological parameter that sets the absolute scale, size and age of the Universe. It is one of the most direct...

Cosmic bursts solve Universe's 'missing matter' problem
... available telescopes at the time. Then, in 2007 the search took an unexpected turn when astronomers discovered a new cosmological phenomenon called a fast radio burst (FRB). These highly energetic pulses of radio emission appear to come from...

New study challenges the assumption that the Universe doesn't spin
... Universe is inflating with no particular direction and that the galaxies in it are distributed with no particular cosmological structure. This assumption is consistent with Einstein’s equations but isn't required by them. However when cosmologists...

The spin of the Milky Way's galactic bar has slowed by a quarter, say researchers
... in significantly more mass than we can see. By fitting a theoretical model of the composition of the Universe and other cosmological observations, scientists think that dark matter makes up about 27 percent of the cosmos and outweighs visible matter...
