Astronomers studying an otherwise “boring” galaxy over a billion light-years from Earth have been surprised to see a powerful storm erupt from its core, an event that will quench any new star formation in the foreseeable future.
Ground-breaking observations have been reported by an international team of astronomers, who is the first to witness the formation of a multiple-star system in its earliest stage. Their findings help support one of several proposed mechanisms by which scientists think these multistar systems might form.
Using data from the Lunar Reconnaissance Orbiter, NASA’s Scientific Visualization Studio has produced a simulation of the side of the moon that we never get to see from Earth.
As crazy as it sounds, we’ve all kind of accepted the part of the Big Bang Theory that says the universe started as a single point around 13.8 billion years ago. The thing is – a lot of theoretical physicists aren’t enthralled with that idea, as a lot of widely-accepted general relativity equations start to break down as you approach the “singularity”.
A small satellite named “Twinkle” will be launched in four years and provide new information about exoplanets, according to a press release from University College London (UCL). The details of the mission that will be lead by UCL and Surrey Satellite Technology Ltd. (SSTL) will be announced Friday at an open meeting of the Royal Astronomical Society.
Eventually, billions or even trillions of years from now, the universe is going to end. Astrophysicists don’t know exactly how the universe will end, but they have some ideas. A group from Munich called Kurzgesagt put together a video explaining the three most likely ways it could happen.
While there’s no prehistoric land hidden at the centre of our planet, as author Jules Verne imagined, the Earth’s core may not at all be like what scientists have led us to believe. Geologists have discovered that the Earth’s inner core – previously thought to be a solid lump of iron – may in fact have its own even smaller core within it.
Supernovae are rare in occurrence, but at the center of an enigmatic nebula lie two stars that astronomers say will eventually end in a fiery, violent supernova. Astronomers believe that the two stars are set in such a tight orbit that they will merge and cause each other’s explosion and death.
Scientists are always trying to learn more about the universe. Sometimes they are trying to investigate the furthest reaches to look for more possibility of life. But they also continue to examine the origin of the universe. And as they continue to do that they learn more about the formation of our galaxy and our planets.
Human expeditions to asteroids and Mars are potentially looming on the horizon, with programs such as Mars One even looking to establish a permanent human colony on the red planet. With the potential for long-term human space travel and habitation, researchers are working to understand the potential effects of remaining in regions with little-to-no gravity for extended periods of time.
The image, taken by Expedition 41 aboard the International Space Station, looks like the fine artwork of some extra-terrestrial, but it’s actually decades old scarred earth and entrenchments of warfare along the Iraq/Iran border.
On February 6, 2015, Jupiter comes closest to Earth on its opposition date, coming to within 404 million miles (650 million kilometers) of Earth. Earth passes more or less between the sun and Jupiter, placing Jupiter opposite the sun in our sky. Astronomers call this event an opposition of Jupiter.
