Till now, one of the unknowns in the blazar physics is to know the exact location of gamma-ray emissions. But, by using the data collected by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) and the Fermi Gamma-Ray Space Telescope, scientists found that the source of the gamma rays that entered into Earth’s atmosphere in April 2015, was actually surprisingly far from the galaxy's black hole. Scientists have found that these gamma rays have been the source of a galaxy PKS 1441+25, which is a rare type of galaxy known as a blazar.
By using the Hubble and Spitzer space telescopes, scientists revealed that so called ‘Hot Jupiters' appear to be strangely dry. ‘Hot Jupiters’ are gaseous planets bigger than our own solar system’s Jupiter orbiting their parent stars closer than Mercury orbits the sun. From past many years, it was believed that these exoplanets must be having water, after all, oxygen, after hydrogen and helium, is the most abundant element in the universe. But, the mystery has now been solved and scientists are surprised with the fact that, Where’s the water?
American space agency NASA’s Earth Polychromatic Imaging Camera (EPIC) has recently captured some breathtaking images of earth. The images provide some visually stunning view of earth.
According to NASA experts EPIC is placed aboard agency’s Deep Space Climate Observatory (DSCOVR), which orbits the sun about 1 million miles from Earth. This huge distance makes it a perfect point to capture earth’s sunlit area every two hours.
NASA’s New Horizons spacecraft has released new images of Pluto and its biggest moon, Charon. Interesting information has been unveiled through these photos and that is changing faces of Pluto and Charon.
Father of Tim Peak, Britain’s first official astronaut to visit the International Space Station (ISS), said he is more worried about the fact that his son will be driving the M27, than his mission to ISS.
The 43-year-old Tim’s journey to the ISS will start when the 162-ft long Russian rocket will blast off from Baikonur Cosmodrome on Tuesday. Tim will also be the first 100% British professional astronaut to leave earth for mission aboard space station.
On Thursday, bad weather delayed the launch of an Orbital ATK Inc. rocket to the International Space Station (ISS). Now, the resupply mission has been rescheduled to take off on Friday.
The mission to the space station is the first of the enhanced Cygnus, which will take about 7,700 pounds, or 3,500 kilograms, of cargo for astronauts living aboard the habitable artificial satellite in low Earth orbit.
Curiosity captured new images with its Mars Hand Lens Imager (MAHLI) camera. Now, it will collect some samples from the sand dunes and study them using its laboratory instruments. It will investigate how the area has changed over the time. According to NASA, the car-sized robotic rover has started examining the sand dunes on the Red Planet.
“The individual dunes of the Bagnold band – which is located along the northwestern flank of Mount Sharp inside Gale Glacier – move up to 3 feet (1 meter) per year, based on observations from orbit”, the space agency explained.
On the eve of Christmas, the season of give and take of gifts, you will now be able to see full moon along with the full snow. Along with the festive of gathering around a table, with bone fire, what else you expect could add and make your day even more special? How about a unique celestial phenomenon for this season, i.e. a full moon? The best thing to note is that as we will celebrate the great Father Christmas, Mother Nature will delight our senses with a show that will be hard to miss.
Stargazers should keep themselves free this weekend if they want to enjoy the mesmerizing show set by the annual Geminid meteor shower, the best celestial event of the year.
Astronomers call it as the best meteor shower in past years because of the number of meteors it produces. This year’s annual show will start on Sunday evening into Monday morning.
The show will most probably start between 9pm and 10 pm and will continue overnight. Experts said it will be easier for stargazers to enjoy the show as this year a crescent moon will set early on Sunday.
Researchers have discovered the best evidence yet for a star to have a cloudy storm. The W1906+40 has been found to be having a giant, cloudy storm akin to Jupiter’s Great Red Spot. With the help of NASA's Spitzer and Kepler space telescopes, the researchers have discovered the L-dwarf that is the size of Jupiter and the storm it has is the size of Jupiter’s Great Red Spot.
