Scientists have just released details of the incredible discovery of 72 previously unobserved galaxies, lying in one of the most studied areas of space, the Hubble Ultra Deep Field (HUDF). The galaxies were identified with the newly launched Multi Unit Spectroscopic Explorer (MUSE), which is part of the European Southern Observatory’s Very Large Telescope (VLT) based at the Paranal Observatory in Chile.
Wouldn’t all your sci-fi dreams come true if there was a celestial body, other than Earth, we could live on, or at least where alien life was found? Well, in a supercool discovery, astronomers from Europe have spotted a planet, Ross 128 b, close to our solar system, about 11-light years away, with a temperate climate and sized similar to Earth. But what seems to have caught the interest of experts is its possible habitability.
The key to finding habitable planets may well lie a lot closer to home than many of us realise. Since 1997, NASA satellites have been observing our own Earth, building up a fabulous resource which shows us exactly what a planet that is capable of sustaining life looks like. This huge repository of information is now helping inform scientists as to some key pointers they should be looking for as they trawl the universe looking for other planets which may hold the potential to support life.
Whilst the sun might look relatively benign from here on Earth, in reality it’s a hugely powerful star which undergoes many storms, some of which scientists are only just beginning to understand. Scientists can now predict the likelihood of coronal mass ejections, or CMEs with relative ease because these events are usually preceded by some kind of warning sign. This can include the presence of more energetic particles, bright flashes or bursts of heat.
The current scientific understanding of the universe and the basis by which it exists involves the concept of anti-matter: a nebulous state that is an exact antithesis of the matter we and everything we perceive is made of. Therefore, an important question that arises from this theory is how antimatter didn’t stop a universe-load of matter existing in the first place. Some prominent researchers conclude that this is due to some fundamental imbalance of particles or forces.
The Great Pyramid of Giza, an Ancient Wonder of the World, is considered an engineering marvel built as a tomb for the pharaoh Khufu. This largest and oldest of the three pyramids is estimated to be about 140 meters tall and 230 meters in width. A structure that attracts millions of tourists per year also surrounds itself with theories and many unanswered questions regarding its age and architecture. Now, yet another mystery has been revealed by this enigmatic structure:
Scientists have just released details of the discovery of ten planets, all of which show promise as potentially habitable worlds. So who knows, perhaps future missions to visit other planets will take us much further afield than Mars in our own solar system.
If you’re looking for the perfect soundtrack to your Halloween party, look no further than NASA’s newly released collection of mysterious noises recorded by spacecraft travelling within our solar system.
The race to Mars is well and truly on, but a major stumbling block so far has been how to create a breathable environment for those brave enough to volunteer as the founding members of any colony which may be established there. Consideration also needs to be given to the fuel required for any return trips from the red planet and whether it may be possible to produce this on Mars itself.
The mission to create a colony of humans on the moon has just received a huge boost – in the unlikely discovery of a cave stretching into the surface of the moon. Scientists suggest that this could be the perfect location for a lunar exploration base. A team of international researchers released details of the find in Geophysical Research Letters, noting that the cave was found through researchers studying data collected by the Japan Aerospace Exploration Agency (JAXA) Kaguya lunar orbiter.
2017 has certainly seen some leaps in the technology and resources available to a handful of organisations that may be most likely to deliver more extensive space travel to more people. This has included a steady increase in the theoretical, experimental and practical research that will underpin how humans and other lifeforms will respond to space flight over longer periods. This includes all normal aspects of human life, including what happens to the bacteria the average person plays host to on an everyday basis.
A solar flare hitting Earth and wiping out electricity grids and satellite communications might sound like something from a science fiction movie, but it’s happened before and scientists predict it could well happen again. A new study suggests that the likelihood is that the Earth will be hit by a serious solar flare within the next 100 years.
In a press conference today, scientists from over 70 different observatories came together to reveal new information about the nature of our universe.
On Thursday October 12, a small asteroid estimated to be between 10 and 30 meters in size is going to be the subject of international attention as a global team of scientists observe its orbit past the Earth. The asteroid, known as 2012 TC4, is due to pass us by at an altitude of around 44,000km (27,300 miles). This is lower than the altitude that the majority of geosynchronous satellites orbit the Earth. Its predicted that TC4 will be closest to the Earth as it passes just south of Australia, at around 05.41 GMT.
Since Albert Einstein first predicted the existence of gravitational waves in his general theory of relativity, astrophysicists have been on the lookout for these mysterious ‘ripples’, which are released due to the collision of huge objects like black holes. These collisions result in an alteration in the curvature of spacetime, which Einstein predicted could be detected here on Earth.
Elon Musk and his company Space X have some grand plans for the future of humanity – with details released last night, at 12:30AM ET, at the International Astronautical Congress held in Adelaide, Australia.
Einstein’s general theory of relatively first introduced the concept of gravitational waves in 1916. Gravitational waves are ‘ripples’ sent out across the universe as a result of massive objects such as black holes merging together and thus causing an alteration in the curvature in spacetime. It’s taken a while though, for scientists to build a detector sensitive enough to detect and therefore confirm the presence of these waves, which by the time they reach Earth can be almost imperceptible.
Cassini-Huygens is probably the most famous deep-space probe humanity has produced. Its launch, a joint venture between the Italian Space Agency, the European Space Agency and NASA, was a major international collaboration intended to send images and other data about Saturn and its many moons back to Earth. However, none of these agencies could have anticipated in full the revelations that Cassini’s sensors and cameras would transmit over its lengthy mission.
The Hubble space telescope has identified many objects in our solar system, with one of its recent missions to help astronomers discover more about a mysterious object in the asteroid belt between Mars and Jupiter. At first glance, this object appeared to be two asteroids orbiting each other, and was assigned as such. But further observations revealed that it also possessed characteristics in keeping with a comet. Astronomers knew that this meant they needed to take a much more detailed look.
Astronomers now agree that at the center of large galaxies, lie supermassive black holes. These black holes usually have a mass greater than a million solar masses. As yet though, the formation of these supermassive black holes has remained somewhat of a mystery. Astronomers have long suggested that perhaps a possible explanation for the sheer magnitude of these black holes is that they may have been formed from a number of smaller, intermediate-mass black holes merging together in order to eventually form a supermassive black hole.
