The ‘young’ Earth may have swallowed a Mercury-like planet billions of years ago, a collision which providing our planet’s layers and generate Earth’s magnetic field creating the perfect conditions required for life to flourish.
On October 12, 2017, the asteroid 2012 TC4 is expected to pass dangerously close to Earth. The exact distance of its closest approach is uncertain as well as the estimated size of the asteroid ramain unknown ~ it vary from 40 feet to 130 feet across, it could be as large as 40m wide – just under the height of Statue of Liberty.
One of the consistently difficult hurdles for space exploration is cost. With dwindling governmental support the initiative has moved toward the private sector.
Underneath some nondescript farmland near Geneva, on the border of France and Switzerland, the world’s biggest and most expensive scientific experiment is ready to re-start. LHC at the Cern laboratory – were preparing to switch it on today for the first time in two years, ahead of the next series of experiments.
According to a report, a 1,000 m wide huge asteroid could pass past earth on Friday. Currently, the asteroid has been travelling at a speed more than 23,000 mph in space. Reports stated that if the mammoth asteroid, 2014-YB35, hit earth it could destroy a country and pose threat to the planet.
The world’s most powerful sub-atomic particle accelerator – the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (Cern) in Geneva – has been given the go-ahead to re-start after being closed for two years of maintenance, now LHC is ready to explain one of the biggest mysteries of the Universe – the nature of dark matter.
How a sunset might look like to a human observer if our Sun was replaced by some of the other stars in our galaxy with different sizes and magnitudes, namely: Barnard’s Star, Gliese 581, Tau Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and Aldebaran. Enjoy this amazing Photo.
We all know and love the moon. We’re so assured that we only have one that we don’t even give it a specific name. It is the brightest object in the night sky, and amateur astronomers take great delight in mapping its craters and seas. To date, it is the only other heavenly body with human footprints. What you might not know is that the moon is not the Earth’s only natural satellite.
Every 250m years the sun, with its entourage of planets, completes a circuit of the Milky Way. Its journey around its home galaxy, though, is no stately peregrination. Rather, its orbit oscillates up and down through the galactic disc. It passes through that disc, the place where most of the galaxy’s matter is concentrated, once every 30m years or so.
Two extraordinary events are underway in February in science and technology, the first in quantum physics and the other in computer security. The Large Hadron Collider at CERN will be brought back online next month to face its next challenge, to seek evidence confirming the validity of extensions to the Standard Model of physics in general, and the ominously-named ‘dark matter’, in particular.
The ancient Earth was a hostile environment marked by unpredictable climate and oxygen-deprived air over 3 billion years ago. Until this week, scientists believed that life forms came into existence, and started using Earth’s nitrogen, around 2 billion years ago. But the new research from the University of Washington changes all these previous theories.
The drought in California, going into its fourth year, has been in the news, especially since California produces much of the country’s food. But a new NASA study, published this week in the journal Science Advances, suggests that the U.S. could be looking at much worse.
