NASA set to test quiet supersonic flights

NASA set to test quiet supersonic flights

Until now, NASA says the plane had simply been called the X-plane and that it has a shape that prevents the shockwaves to come together, which is what produces that dreaded booming sound. NASA says that it will continue to carry out testing flights over other US towns in order to gather more ground information; this of course will happen only after Lockheed Martin is able to properly construct the aircraft and NASA is able to establish the proper noise credentials.

This is the First Confirmed Picture of a Newborn Planet

The newborn sits within a 5.4 million-year-old solar system, orbiting a star called PDS 70. Within these so-called protoplanetary disks - which can be up to 1000 astronomical units wide (1 AU is the average Earth-Sun distance of 93 million miles) - particles of gas and dust clump together over time, slowly but surely forming larger bodies that may eventually reach planetary status.

NASA spacecraft sending back close-ups of dwarf planet Ceres

NASA spacecraft sending back close-ups of dwarf planet Ceres

Infrared instruments aboard Dawn established the brighter materials are made of sodium carbonate, a salt-based compound commonly used on Earth for softening water. NASA expects the spacecraft to last just another few months. The new elliptical orbit, which takes the probe from a little more than 20 miles (33 kilometers) above Ceres to a maximum distance around 2,500 miles (4,000 kilometers) will force Dawn to burn its remaining propellant faster, limiting its lifetime.

Extreme heat warning issued for Canada Day long weekend

He said that while the mercury will remain "elevated", overnight lows in the mid-teens will provide relief to many.

Astronomers Believe They Have First Image of Newborn Planet

It's carving out a path through the disk around the star, which is in the Centaurus constellation. An image of a newborn planet around PDS 70, a dwarf star 460 light-years from Earth . While a newborn planet might sound like an interesting place to visit, you most certainly wouldn't want to set foot on PDS 70b any time soon. The data suggest that the planet's atmosphere is cloudy.

Miriam Kessler, who headed up the group that found this awesome event, told the Independent: "These discs around young stars are the birthplaces of planets, but so far only a handful of observations have detected hints of baby planets in them".

Start planning now for longest lunar eclipse of the century

By comparison, the average distance between Earth and Mars is 225 million kilometres. "On the night of the lunar eclipse , Mars is quite close to the Moon (in the sky)". The "blood moon" eclipse is on July 27. (North American observers - who will still be in daylight at that time - will need to watch the show on webcasts.) Including the partial phases of the eclipse, the moon will be in the Earth's shadow for almost 4 hours. Consulte Mais Informação
