New imaging reveals colossal cosmic web lurking in dark distant universe

On the largest scales possible, the universe resembles a web of light spun by an inconceivably large spider. Now, astronomers have detected very faint light from these cosmic web filaments in the deep, dark, distant universe.Continue ReadingCategory: S… Continue reading New imaging reveals colossal cosmic web lurking in dark distant universe

Pair of invisible stars found locked in tight 17-hour orbit

Astronomers have discovered a bizarre star system containing two ultra-cool dwarf stars that are so close together they orbit each other in less than a day. Oh, and they’re invisible to the human eye.Continue ReadingCategory: Space, ScienceTags: Astron… Continue reading Pair of invisible stars found locked in tight 17-hour orbit

“Monster” black hole may be the closest to Earth found so far

Astronomers may have discovered a monster black hole that’s one of the closest to Earth known. With a mass equivalent to 12 Suns, the black hole was found to be quietly lurking “practically in our backyard,” according to the team.Continue ReadingCatego… Continue reading “Monster” black hole may be the closest to Earth found so far

“Cow” and “Koala” lead explosive new class of space signals

The universe is full of powerful explosions from various sources, and now astronomers have described a brand new class of space signals. Named fast blue optical transients (FBOTs), these events are very bright and throw off incredible amounts of energy… Continue reading “Cow” and “Koala” lead explosive new class of space signals

Ancient white dwarf explosions seem to disobey long-established "rules"

White dwarf stars have mostly been thought to follow very specific “rules” – if they’re over a certain mass limit, they’ll explode in a supernova with a very predictable brightness and time. But now Caltech astronomers have found a strange tw… Continue reading Ancient white dwarf explosions seem to disobey long-established "rules"

Astronomers pinpoint location of mysterious radio signal across the universe

Fast radio bursts (FRBs) are one of the most puzzling mysteries of the space age. These one-off, millisecond-long signals pour in from all corners of the cosmos, and so far nobody’s been able to figure out what causes them or where they’re ev… Continue reading Astronomers pinpoint location of mysterious radio signal across the universe

Europa's ocean may be more Earthlike than previously thought

Color composite view combines violet, green, and infrared images of Europa in natural color (left) and ...

A new study by researchers at Caltech and NASA’s Jet Propulsion Laboratory in Pasadena, California, indicates that the subterranean world ocean on Jupiter’s moon Europa may be more Earthlike than scientists believed. Visible-light spectrographic analysis show that yellow stains on Europa’s icy crust are common table salt, suggesting that the Europan ocean may be similar to its terrestrial counterparts.

Astronomers Discover Rare Kilometer-Sized Object in Outer Solar System

“We didn’t even have enough money to build a second dome to protect our second telescope! Yet we still managed to make a discovery that is impossible for the big projects.” Continue reading Astronomers Discover Rare Kilometer-Sized Object in Outer Solar System

Astronomers Discover Incredibly Rare ‘Fossil Cloud’ Created Minutes After the Big Bang

The fossil cloud is only the third of its kind ever seen by astronomers, but could pave the way for their systematic discovery in the future. Continue reading Astronomers Discover Incredibly Rare ‘Fossil Cloud’ Created Minutes After the Big Bang
