Asteroid Apophis is expected to be visible in the Earth sky on Wednesday, Jan. 9. The asteroid is quite far relative to the moon's distance from the planet. But in 2004, scientists feared an eventual impact with this 270-meter rock in space.

National Aeronautics and Space Administration (NASA) astronomers are getting ready for asteroids and comets that could flyby near planet Earth this 2013. NASA’s deep-space radars at Goldstone, California and Arecibo, Puerto Rico will reportedly monitor space on January 9 for a particular flyby of an asteroid identified as 99942 Apophis at approximately 14.5 million kilometers away.

Elon Musk, the co-founder of PayPal, a global e-commerce business, is planning to build a small city on planet Mars. However, there is a small catch - only 80,000 space explorers would be allowed to live on the red planet, and they must be vegetarians.

NASA’s Curiosity rover captured the image of a flower-like object on Mars, but scientists are quick to announce the object was just a rock or "part of the rock" in the image. Check out the accompanying photos to see for yourself.

World Wildlife Foundation (WWF) Australia insisted over the weekend that Queensland does not need new coal ports in and near the Great Barrier Reef. WWF based its assessment on the state government's Great Barrier Reef Ports Strategy Economic Analysis that said coal ports in the area are operating at only 52 per cent of their planned capacity.

Professor Stephen Hawking, who has appeared in the hit CBS sitcom "The Big Bang Theory," is featured in a new Go Compare advertisement. The brilliant scientist showed once again that he has a knack for pulling off funny "Bazinga" moments.

The 2013 New Year’s Day coincided with “natural fireworks” erupting from the sun, which is approaching “solar maximum,” during which there will be more intense solar flares.

Like previous yearend holidays, 2012 ended with a lot of feasting across different nations and continents. The menu varied from national favourite dishes to traditional yearend holiday food ranging from pasta to fresh fruit.

The 2013 Quadrantid meteor shower will only last for a few hours at its peak time on January 3. In a released NASA statement, the major sky gazing time will still differ on location so viewers who wish to experience the spectacular meteor display really need to wake up in the early hours of the morning.

Australian astronomers are gunning to detect some 700,000 new galaxies via the $105 million Australian Square Kilometre Array Pathfinder (ASKAP) located in the remote desert region of Western Australia.

The skies will welcome the year 2013 with a spectacular show when the Quadrantids meteor shower peaks in the early morning hours of January 3, 1013. The meteor shower is expected to reach its maximum rate of 80 meteors per hour with the possibility of exceeding to more than 200 meteors per hour.

Although the last Doomsday prediction that the world would end on Dec 21, 2012 was an epic failure, red-faced Mayans would not prevent other apocalyptic forecasters from prophesying end times.

A study of the activity in the South China Sea reefs had shown the coral reefs in the area greatly deteriorated at the expense of the economic growth activities in mainland China.

Australian Research Council Centre of Excellence for Coral Reef Studies and South China Sea Institute of Oceanology researchers blamed China's economic boom for the shrinkage by at least 80 per cent of coral reefs in the region over the past three decades.

The idea of spending Christmas and New Year in space may sound cool but the six NASA astronauts pay the price of celebrating it away from their loved ones.

Scientists from the West Australian Department of Fisheries are looking into the odds that the rising high temperature of the sea waters in the state are what caused sharks to swim near the shore and eventually attack humans.

With the end-of-the-world scenario now over, Australians would likely be able to concentrate on the Christmas and New Year celebrations, which would mean a lot of food preparations. It also means a lot of wasted food. Throughout the year, Aussies waste $8 billion worth of food, said a study by Do Something!, released on Sunday. Based on an estimated volume of four million tonnes of food thrown away yearly, Do Something! founder John Dee reckoned the value of per capita wastage at $1,036.

Despite the sun not flaring, planets not aligning and asteroids not hitting Earth, no mass suicides occurred on Friday as feared by national authorities. Credit goes to local and national leaders for taking steps to prevent the feared mass suicides.

The world prepared, but the Mayan prediction that the world would end on Dec 21, 2012 did not come to pass. With the global buzz that accompanied the run-up to the Doomsday, the date would definitely be added to the list of end-of-the-world predictions that fizzled out.

Australian scientists sounded alarm on the possibility that catastrophic tsunami waves could swamp Queensland coastlines in the event of a very powerful earthquake hitting the region.

In the combined U.S. Air Force and National Oceanic and Atmospheric Administration (NOAA) Solar Geophysical Activity Report and Forecast copy released on December 20, there is no space weather threat on the much talked about doomsday end of the Mayan Calendar today, December 21.

In the event that the 2012 Mayan Calendar End-of-the-World scenario would happen on Friday, majority of the human race will likely migrate to nearby areas safe for living until it is clear and safe to go out again. But is there really a shelter that is 100 per cent perfect against anything that could happen in a cosmic catastrophe?

In two days, the world would finally know if the Mayan prophecy would lead to destruction or prosperity. In a run-up to Dec 21, preparations have been made by doomsday preppers just in case something does happen globally. It is expected that if the Apocalypse scenario would take place, chaos will hit the economy, health, welfare, shelter, food, and energy sectors.

Astronomers have spotted five possible planets within Earth's vast neighborhood. One of these relatively nearby planets could be habitable, according to a study. The five astronomical bodies have yet to be officially called planets because studies are still ongoing. But a couple of things can be shared with the public as early as now.

Human doll Valeria Lukyanova seems to be ready for the much-talked about apocalypse on December 21 as per the Mayan Calendar.

A walking catfish, a devilish-looking bat, a singing frog, a ruby-eyed pit viper and a two-legged lizard are among the newly-discovered species in the Greater Mekong region that the World Wildlife Fund for Nature (WWF) has listed on its new report titled Extra Terrestrial.
