That image of Luke Skywalker staring out from his home planet of Tatooine in Star Wars: Episode IV – A New Hope is iconic. This is mostly because you see Luke staring up at two sunsets, which we all know can’t happen in real life. Or could it?
A former NASA engineer claimed that he saw a nine-foot tall alien on his 1991 space mission. The UFO conspiracy theorist claimed to have been NASA’s engineer for 35 years and insisted the story of super-size humanoid making contact with colleagues was true.
Our universe has been in existence for nearly 14 billion years and science has led us to believe it will keep existing for many billions more. So, will the universe expand forever, or will it one day collapse under the influence of its own gravity?
Dark matter is one of science’s great mysteries. It makes up an enormous amount matter in the universe, it is invisible, and it does not correspond to anything in the realm of our experience. Different theories compete for an explanation, but so far none of them has prevailed.
Don’t let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area – think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape.
Astronomers have obtained direct observational evidence for the first time of a supermassive black hole, at the center of a large galaxy, powering huge molecular outflows from deep inside the galaxy’s core removing massive quantities of star-making gas thereby influencing the size, shape and overall fate of the host galaxy.
Scientists for a long time were fairly certain that at one point in the universe’s history, Mars was host to forms of life, but that theory might have just been confirmed by NASA’ rover. Curiosity rover tasked with surveying the Red Planet has come up with surprising results when gathering samples from the soil and the environment of Mars.
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.
After two years undergoing upgrades, the CERN Large Hadron Collider is gearing up for a new round of experiments, and things could get interesting this time. If scientists detect miniature black holes when using the Large Hadron Collider it could prove the existence of parallel universes and possibly disprove the Big Bang theory.
This #Infographic puts in to perspective just how big the universe is. From the city you live in, to the state, country, continent, planet, solar system, galaxy etc. Visualizing the universe and its visible area puts in to perspective just how small we are. With the help of Hubble space images, and advanced high definition cameras from NASA, we are able to see the universe how we never could in the past.
Some of seventeenth century’s greatest astronomers, including Hevelius — the father of lunar cartography — and Cassini, carefully documented the appearance of a new star in the skies in 1670. Hevelius described it as nova sub capite Cygni — a new star below the head of the Swan.
As astronomers have gained the ability gaze at far-off exoplanets, they have started to realize our solar system is more unique than they could have imagined. Many other alien’ systems have ‘super-Earths’ and other planets in tight orbits close to their star, but ours does not. And now we might know why.
