Before the moon, there was water on Earth. This was the conclusion a group of scientists arrived upon after they studied lunar rocks from all six of the Apollo missions and investigated volcanic rocks from the Earth’s oceans.
Astronomers predict the sun will reach the end of its life in approximately 10 billion years, according to new research.
Fast radio bursts (FRBs) are radio emissions characterized by their intensity and briefness.
Space exploration is a small part let’s see if we can do this, and a large part let’s find out what we learn if we do this and that.
Round 5 a.m. on a Tuesday this past May, Tabetha "Tabby" Boyajian sat staring at a laptop, cross-legged on her couch in the living room of her Baton Rouge, La., home. The coffee table was cluttered with the artifacts of an all-nighter: an empty wine glass to calm her nerves alongside an empty coffee mug to fuel her through the night.
NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit). Slightly warmed by the remote Sun, it has already begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma, enveloping a tiny, solid nucleus of frozen gas and dust. These observations represent the earliest signs of activity ever seen from a comet entering the solar system's planetary zone for the first time.
Blackhole1 The apparent development of a large void of some billion light-years in diameter in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole" rather than hypothetical dark matter responsible for the phenomenon described as the expanding-accelerating universe. This radical theory of cosmology suggests that stars at the edge of the Hubble length universe are being consumed by a universe-in-mass black hole.
The upcoming solar eclipse on August 21st could be a sign of the end of times, say some Christians
A huge total solar eclipse will take place over the United States this month and for some Christians, it's a clear sign from God that the last days prophesied in the Bible are upon us.
Cassini found molecules said to be 'vital stepping stone' to complex molecules The researchers say these may be the building blocks for life-creating molecules The discovery could help to explain the processes that led to life on Earth
In the hazy atmosphere of Saturn’s moon Titan, scientists have discovered molecules thought to be the building-blocks of the complex organic compounds that make life possible.
A good rocket launch site has a few important characteristics. An unpopulated patch of land near an ocean is preferable, so no one gets showered with wayward bits of flaming metal. It’s also nice if it’s on the equator—like all spheres rotating on an axis, the Earth spins fastest in the middle, which provides rocket boosters with extra oomph. In other words, the best sites tend to be in remote, tropical locations.
