Massachusetts Institute of Technology (MIT) researchers have come up with a new way of predicting the onset of rogue waves, also known as killer waves.

So far, efforts for their prediction were restricted to expensive, inefficient, and time-consuming computer models that were focused on mapping out every single wave in a water body.

Published on February 11, in the Journal of Fluid Mechanics, the latest method is simpler, easier, and faster. Aim of the new method is to give sailors and sea-platform workers a time range of two to three minutes to get ready, prepare, including closing down vital systems.

On Monday, scientists said that with the rise in sea levels, putting cities from New York to Shanghai in danger, the economic damage is going to increase even faster.

In a study, scientists wrote that severe floods whipped up by storms will become ever more costly for cities with the ocean levels edging up around the coasts worldwide in coming decades. The study may help guide governments in preparing a budget to save everything, ranging from buildings and basements to metro systems.

While speaking to Reuters, co-author Juergen Kropp, a member of a team at the Potsdam Institute for Climate Impact Research, said that the findings have shown that the damage from sea level rise increases at a fast pace in comparison to sea level rise itself.

NASA's Hubble Space Telescope has clicked a picture of a stunning blue bubble in space, a star known as WR 31a wrapped in blue wonder. The photograph is possibly the most detailed picture of the star ever clicked.

The Hubble Space Telescope has always been in limelight for bringing captivating images from space like birth of a star, star death and even that of the first forecasted supernova explosion. The telescope has acted as our planet’s window to the world outside. And it has sparked interest again with the so-called ‘blue bubble’.

The blue bubble is surrounding a Wolf-Rayet star present at a distance of around some 30,000 light years from earth and has been discovered in the Carina constellation.

On February 28, SpaceX cancelled the launch of a commercial communications satellite seconds before liftoff, and postponed the mission once again. Launch controllers said that SpaceX's Falcon 9 rocket was planned to launch the SES-9 satellite from Cape Canaveral Air Force Station in Florida at 6:46 pm yesterday, but the initial liftoff time was delayed back 35 minutes as a boat drifted into the mission's ‘keep-out zone’.

Falcon 9's engines started firing up at 7:21 pm EST, however, they stopped the moment countdown clock was about to reach 0.

SpaceX founder and CEO Elon Musk said that the rocket could have blasted off yesterday if there wasn’t any stray boat.

An interactive session was conducted between students of City of Norwich School and British astronaut Tim Peake. The session, which took place yesterday, saw the 10 curious youngsters asking varied question from Peake as he passed 250 miles overhead aboard the International Space Station.

Student and amateur radio enthusiast Tim Hare, 15, were given the task to establish contact with the ISS using the specially designated call sign. After a few seconds, the connection was obtained and students were able to hear the muffled voice of Major Peake, 43. He appeared to be floating on screen.

On Friday, investigators said that monarch butterflies have made a big return in their wintering grounds in Mexico, after witnessing severe declines in recent years. Scientific community and media raised awareness about declining numbers of Monarch butterflies.

This season, the region covered by the orange-and-black butterflies in the mountains west of Mexico City was over three and a half times greater in comparison to last winter. The butterflies clump so heavily in forests they are counted by the area covered by them to estimate their number.

In recent years, before recovering in 2015, the number of monarchs that migrate covering a distance of 3,400-mile from the United States and Canada fell steadily. The most recent winter was even better.
