A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

                         ESA’s (European Space Agency) Mars space craft points to a pond of liquid water buried under layers of ice and dust in the south polar region of Mars. Evidence for the Red Planet’s watery past is prevalent across its surface in the form of vast dried-out river valley networks and gigantic outflow channels clearly imaged by orbiting spacecraft. Orbiters, together with landers and rovers exploring the martian surface, also discovered minerals that can only form in the presence of liquid water.           (  Download Powerpoint ) The presence of liquid water at the base of the martian polar caps has long been suspected but not observed. Scientists surveyed the Planum Australe region  (the blach spot on image A) using the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument, a low-frequency radar on the Mars Express spacecraft...

The interaction between galaxies is an on going process in universe. However the merging of big galaxies with each other on average once over the past 9 billion years. But Small galaxies were coalescing with large galaxies more frequently. In fact, our own Milky Way galaxy had several such mergers with small galaxies in its recent past. In the combination of galaxies there is no collision of stars with eath other, it is the dust and other material which collapse and billions of stars are born, mostly in groups and clusters of stars. Some of the images of colliding galaxies taken by hubble This is image of a pair of interacting galaxies called Arp 273. The distorted shape of the larger of the two galaxies shows signs of tidal interactions with the smaller of the two. It is thought that the smaller galaxy has actually passed through the larger one. This nearly 300 million light years away from earth. And a part of Constellation "Andromeda" Hubble has captured a...

Have you ever dreamed of going to the Moon? Imagined you were riding alongside Neil Armstrong and Buzz Aldrin as they piloted the lunar lander. Look around to see Earth out one window and stars lighting up black space from another. Now Apollo 11 VR going to make your imagination real by enables users to relive the Apollo 11 mission and take some of the first steps on the Moon—though not the very first, because Neil Armstrong is a few feet ahead, kicking up lunar dust and proclaiming, “... one small step for a man, one giant leap for mankind.” This all is going to done by Virtual technology. The combination of a virtual reality environment and NASA data and media resources helped Immersive VR Education make its app a larger-than-life experience. It has received widespread critical and popular acclaim, including multiple awards, and has been purchased by more than 40,000 users. NASA has an amazing trove of data about the Apollo lunar missions available online. This includes...

Jupiter, the fifth planet from our Sun and the largest planet in the solar system – more than twice as massive as all the other planets combined, has 79 moons including 12 new discovered moons. On Jul. 17, 2018, scientists announced they had discovered 12 new moons orbiting Jupiter. That raised Jupiter’s total number of moons to 79—the most of any planet in the solar system. Fifty-three of the moons are confirmed and named; the other 26 are awaiting official confirmation of discovery before they are named. Jupiter's four largest moons—Io, Europa, Ganymede and Callisto—were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope. These four moons are known today as the Galilean satellites, and they're some of the most fascinating destinations in our solar system.  Io is the most volcanically active body in the solar system. Ganymede is the largest moon in the solar system (even bigger than the planet Mercury). Calli...

This is the Andromeda galaxy — otherwise known as M31. This is the neighbouring galaxy of Milky way galaxy (our own galaxy). This is nearly 2 million light years away from earth. This is a NGC 7640 i. e. barred spiral type galaxy. These are recognisable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s centre. This is the part of Andromeda constellation. This is the image of the beautiful barred spiral galaxy NGC 1300.  NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. This 60 million light years away from the earth and belong to the Eridanus Constellation. This is spiral galaxy Messier 77 — a galaxy in the constellation of Cetus, some 45 million light-y...
