New research in to how Earth's atmosphere evolved over time could hold the key to detecting life on exoplanets, according to scientists from the University of St Andrews and Cornell University.
The new study, published in The Astrophysical Journal, details how Earth's atmosphere evolved over time and how this corresponds to the appearance of different forms of life.
Founded in 1919, the International Astronomical Union is the body charged with officially naming the objects in our universe and "safeguarding the science of astronomy." Here's what they have to say about the names of celestial objects.
I've had an interest for a while in ridiculously old science fiction, such as Margaret Cavendish's 1666 novel The Blazing World, as well as science fiction written by prominent scientists, such as Simon Newcomb's His Wisdom the Defender (1900), Robert Williams Wood's The Man Who Rocked the Earth (1915), and Fred Hoyle's The Black Cloud (1957). But if I want to combine ridiculously old and prominent scientist, there's no book that can beat Somnium, written by Johannes Kepler in 1608!
Often billed as the earliest science fiction novel, Somnium provides probably the earliest descriptions of a journey to the Moon and the beings that live there.
A team of Chinese researchers has revealed a design for a hypersonic jet that they claim could transport passengers from China to New York in a "couple of hours."
Researchers from the Chinese Academy of Sciences discussed details of the four-winged I-plane in a paper published in the Physics, Mechanics, and Astronomy journal.
A new hypersonic aircraft could ferry passengers anywhere in the world in under three hours.
Travelling at up to 3,800 miles an hour, more than six times the speed of a typical commercial jet and twice as fast as a supersonic aircraft, it has been developed for the Chinese military, but could be used for passengers.
A new Hubble Space Telescope image of a celestial object called the Ant Nebula may shed new light on the future demise of our Sun. The image is available at http://hubblesite.
Back in 2016, an astronomy enthusiast named Vctor Buso decided it was a good night to test a new camera on his telescope. The test went well enough that hardware in space was redirected to image what he spotted, and Buso now has his name on a paper in Nature.
A team of Chinese researchers has claimed to have designed a hypersonic jet that could travel at 6,000km/h, five times faster than the speed of sound.
The team from the Chinese Academy of Sciences said the plane would be able to transport passengers and cargo from Beijing to New York in two hours - the journey currently takes an average of 13 and a half hours.
Some children just love space while others may be intimidated by its vast expanse of the unknown. It can be both fascinating and frightening at the same time, but it takes children with great imaginations and determination to have big dreams that will shape the future of life both here on Earth and further afield.

The big weather story in February has not been snow, but the astounding heat. The Danish Meteorological Institute has a station on the Arctic Ocean in Northern Greenland.

The moment he saw the brilliant light captured by his camera, it all clicked for Victor Buso: All the times his parents woke him before sunrise to gaze at the stars, all the energy he had poured into constructing an observatory atop his home, all the hours he had spent trying to parse meaning from the dim glow of distant suns.
In many moments you search and ask yourself, why do I do this? Buso said via email.
Victor Buso was looking forward to testing his new camera on September 20, 2016. The locksmith and amateur astronomer waited for nightfall and headed out to his rooftop observatory in the city of Rosario, Argentina, where his 15.
Victor Buso is a locksmith. He spends his days fiddling with locks and keys, and in his spare time he stares into the heavens in the observatory he built on the top floor of his own home.
It will take only a couple hours to travel from Beijing to New York at hypersonic speed," researcher Cui Kai said in a paper published in February by Science China Press in the journal Physics, Mechanics and Astronomy. Researchers are planning for the plane to reach speeds of nearly 6,000 km per hour.
Galaxies have supermassive black holes at their centersour Milky Way, for example, has its own 4-million-solar-mass one, Sagittarius A*. Some astronomers have previously thought that there's a simple relationship between the galaxy's size, the black hole's mass, and how much light the black hole spits out while it eats up the things surrounding it.
Amateur astronomer Victor Buso was testing his camera-telescope setup in Argentina back in September 2016, pointing his Newtonian telescope at a spiral galaxy called NGC613. He collected light from the galaxy for the next hour and a half, taking short exposures to keep out the Santa Fe city lights.
A 45-year-old telescope is going to get a high-tech upgrade that will enable it to search for answers to the most perplexing questions in astronomy, including the existence of dark energy, a hypothetical invisible force that might be driving the expansion of the universe.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe an active galaxy with a strong ionized gas outflow from the galactic center, a team led by Dr. Yoshiki Toba of the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan) has obtained a result making astronomers even more puzzledthe team clearly detected carbon monoxide (CO) gas that is associated with the galactic disk, yet they have also found that the CO gas which settles in the galaxy is not affected by the strong ionized gas outflow launched from the galactic center.
The president's recently released Fiscal Year 2019 budget gives NASA an overall increase in fundingcertainly something to celebrate in the current fiscally constrained environment. Clearly, however, with so much NASA could do that is inspirational, important and innovative, there will always be choices and tradeoffs to be made.
