NASA's TESS Spacecraft begins hunt for exoplanets

from pixabay In our own galaxy there are billions of planets. Never discovered by humanity  Kepler space telescope launched in 2009 found thousands of planets with different features but recent news confirms that Kepler space telescope journey will soon come to an end. Click here to know more about Kepler space telescope The Kepler space telescope found new planets in a single patch of Milky-way galaxy. On April 18, 2018 a new spacecraft lift off from Cape Canaveral. Launched by Space X falcon 9 into a unusual super elliptical orbit of similar distance between earth and moon.

TESS consist of four cameras which can cover a swath of the sky  96° tall .Dividing the space view in various sections like slices of orange. The TESS Spacecraft view each space view section in 27 days and move to another this way it will complete all the virtual

Source behind dust storms and shut down of NASA's rover on mars found by scientists

The fourth planet from the sun, Mars, is a planet covered with dust not only on surface but in its atmosphere also. But what is the source of this dust?   This always remained a question in past.Study published by space scientists in journal Nature communications got the answers for this question. They found a 1000 kilometres long geological formation near the Mars's equator . Scientists involved in this study found same ratio of major constituent elements of the surface feature and in the atmosphere of Mars They named this geological formation Medusae Fossae Formation . The periodic erosion of Medusae Fossae formation creates dust. This dust in atmosphere from this giant deposit is reason of pollution on Mars explained by one of the co author Kevin Lewis assistant professor of earth and planetary science at John Hopkins University.

Why does the moon appears blood red during a total lunar eclipse?

Photo by  hezron salawane  on  Unsplash Many places on earth witnessed the total lunar eclipse and we enjoyed it. But do you know why this moon appears blood red like mars? The reason for red colour of Mars is that it contains Iron oxides which is nothing but rust on its surface. What about moon? The answer for this is completely different and interesting. To completely understand this phenomenon we have to understand what is lunar eclipse is all about.  When the sun, earth and moon come into one line in space such that earth covers the moon completely then it is termed as total lunar eclipse.A complete shadow ( umbra ) all over the moon.  The indirect light through earth gets bent through our atmosphere which is way beyond from our earth surface causing two area of partial illumination(penumbra) . When the moon orbits around earth from area of partial illumination it gets darker and finally completely comes into the shadow of earth

Scientists found aquifer on planet Mars

A team of scientists found evidence of underground aquifer on the red planet. They got radar signatures from the Mars express orbiter which is an European spacecraft launched in 2003 in mars orbit for conducting research. The radar signatures acquired from the orbiter are similar to those what we get for underground aquifer on earth. This discovery substantially increase the possibility of life on the red planet.  They found those radar signatures when they were scanning ice caps at South Pole of Mars with the help a probe radar instrument named Marsis fitted on the orbiter. They found a 20 km or 12.4 miles wide water body 1.5 km beneath the glacier. The detailed study is published in  Science  on July 25,2018. It is interesting to know that there are some bacteria which can live in very harsh regions like glaciers in Antarctica and Greenland . So there are possibilities that we find some kind of habitable species in that big water pools.  Since here wat

New study claims that aliens might have lived twice on the moon

Earth's one and only natural satellite have many secrets which are to be revealed.Our moon in ancient times was suitable to support life twice ,one 4 billion years ago and again in 3.5 billion years ago suggested by a study at Washington state University. According to the study it is believed that meteorites from earth with living cells and microbes were carried to the Moon. This was published in the Monday edition of journal Astrobiology . Two planetary scientists have stated in there study that during landing of meteorites on Moon created heat enough to melt ice water in the surface of the moon in water vapours and gases which spewed out from the moon surface and form water pools on moon. The study also stated that there was also stable atmosphere at that time with magnetic field wrapping whole moon enough to safeguard organisms on the moon from solar winds. Dirk Schulze Makuch an astrobiologist at Washington State University said that "There could have ac

Andromeda Galaxy M31 ate sibling galaxy M32 and now it is coming for us

Photo by  Bryan Goff  on  Unsplash Once Milky Way galaxy had a sibling which get shredded and swallowed by neighbour galaxy 2 billion years ago. The cannibal galaxy is Andromeda which is neighbour galaxy of our Milky Way. There was a survey going on the stars in faint halo around Andromeda galaxy and they found some interesting results. For those who don't know what is halo? Halo is a cloud of  gas and other matter surrounding and captured by the gravitational field of a large diffuse astronomical object, such as galaxy or cluster of galaxies.  Photo by  NASA  on  Unsplash Scientists created a whole events happened 2 billion years ago on the basis of this survey. The earlier theory which suggested that the halo consist stars of hundreds of small galaxies shredded and consumed. Latest New theory published in Nature Astronomy improvised and corrected the previous one. The new theory based on the survey tells that the halo of Andromeda galaxy cons

Purdue university's scientists create world's fastest spinning man made object

World's fastest spinning man made object Scientists create world's fastest spinning man made object. The object precisely is not a object but a nano particle which is in dumbbell shaped . The nano particle is made up of silica and was levitated by using laser in vacuum .  The noted rotation per second (rps) of the nano particle was about 60 billion rps .  Scientists behind this invention are Tongcang Li and Jonghoon Ahn .  Tongcang Li is assistant professor of physics and astronomy and also serve as assistant professor in computer engineering and electrical engineering in Purdue University .  According to Tongcang Li the dumbbell shaped particle was levitated in vacuum with using laser work.  The laser used having capability of working in a straight line and in circle helped in finding two motion of the nano particle   When the laser work in straight line the nano particle vibrates .  When the laser work in circle the dumbbell spins .  The spinning dumbb

How Parker Solar Probe will withstand Sun's heat ?

Sun may look calm and beautiful from our earth but it is one of the most ferocious body in our solar system, a body whose mass continuously rises ,  having millions of nuclear reactions going every second , tingling magnetic lines sun also have strong and constant winds flowing with speed of million miles per hour . Since it is the only star in our reach to study but it is still very difficult to study its behaviour So how? Parker Solar Probe The answer is Parker solar probe made by NASA which will blast off this year to a long journey of around 4 million miles(6.4 million km) from the earth to the sun. The temperature of sun which can rise up to 1 million degree Fahrenheit is strong enough to melt anything approaching it. So how will our small probe will withstand this harsh surrounding? But still the temperature of the solar panels and elements still can go to about 2498 degree Fahrenheit (1370 degree Celsius) so there is necessity to cool d

The second man to walk on moon once punched a man for calling moon landing hoax, watch video

When Buzz Aldrin lost his temper As we all know that Buzz Aldrin the man who was one of the member of Apollo 11 crew , that landed on the moon on July 20, 1969  is very humble man. But there are some moments in our life which change our nature. The same thing  happened with one of our heroes of Apollo  mission Buzz Aldrin . Buzz Aldrin punched the man right on the face of  conspiracy theorist who was repeatedly saying to the astronaut to "swear on the bible"  Many media spokes person were there when this event happened. A guard of the building also came near to stop him and take him away. According to the conspiracy theorist (the guy) Apollo moon mission was fake a hoax. Buzz Aldrin tried to avoid the men and at last he punched on his face. Many flat earth organisation use this video to prove that Apollo mission was hoax

NASA's Chandra X-ray observatory may have observed star consuming a planet for the first time

There are infinite number of stars in our universe. It is always remained an attraction for cosmologist to observe there behaviour. Many observatories are made by space agencies to study astrology and cosmology one of them is NASA's Chandra X-ray observatory  It is dedicated in observing behaviour of stars and planets in  our galaxy  there are many evidence which shows that a star can consume planets. Well,The New report from NASA on findings of  NASA's Chandra X-ray observatory which says that they have observe a star in our Milky Way Galaxy around 450 light years away from our earth. the star which which is named RW Aur A is been in consideration of scientist since 1937 . the curiosity in this star increased due to fading of its optical light for few decades and brightening again.  But in recent times the frequent dimming of light took attention of scientists A team of scientist with  NASA's Chandra X-ray observatory  observed that the star was

Ninth mission of Blue Origin breaks its own test flight record, reaches 120 km altitude during crew escape test

The ninth launch took place in Texas facility of Blue Origin. Mission objective was safe landing of crew when any anomaly occur at any time  during the launch thus it was a pad abort test. Jeff Bezos led startup tested a live separation test of its crew capsule from the rocket booster. The duration of launch lasted for 2 min and 30 sec . The mission went successful and the crew capsule touched the altitude of 120 km altitude . This mission was the third mission of New Shepard . The mission went as expected by company with complete mission success. The vehicle attained a top speed of 3,598 kmph . The crew capsule seat was occupied by a mannequin(dummy) as passenger . In the test dummy astronaut experienced 10 Gs which is in safe limit. The crew capsule fired its escape motor at right time. As the whole launch vehicle(New Shepard) was based on reusable launch vehicle technology the capsule and booster can be  recovered safely. The capsule uses two parachute

12 new moons discovered around the Jupiter, two of them may collide

Head on collsion between two Jovian moons As we all know the gas giant Jupiter's have already so many natural satellites riding in its orbit mostly in retrograde which means that they revolve in opposite direction of the Jupiter's spin.  Findings of 12 new moons by American Astronomer team with help of Cerro Tololo Inter-American Observatory in Chile in march last year. Now the total amount of Jovian moons orbiting Jupiter is 79 more than any known planet in our cosmic neighbourhood. These discoveries were made by astronomers when they were hunting for a ninth planet beyond the orbit of Neptune. 9 of them are retrograde circling in outer orbit and take 2 years to complete one rotation. The 2 other moons are prograde and are so much close that they are heading towards moon to become small debris due to Jupiter's gravitational field. Here prograde means moons that revolve in same direction of Jupiter's spin. The 12th moon named ' V

Founder of Modern Big Bang Theory, Belgian Astronomer Georges Lemaitre(Born on July 17,1894)

Who was Georges Lemaitre? Georges Lemaitre is also known as founder of Modern big Bang Theory . Georges Lemaitre was an astronomer and cosmologist born on 17 July 1894 in Charleroi , Belgium According to Georges Lemaitre the observable universe began with an explosion of a single particle ( Super-atom ). Georges Lemaitre also proposed that the universe is not finite and it is continuously expanding , based on Einstein theory of general relativity . The Statement was observationally confirmed in 1929 by Edwin Hubble and named   Hubble's law . Also did research on cosmic rays and Three-Body problem . Notable Work of Georges Lemaitre Evolution of The Universe (1933) The Primeval Atom: An Essay on Cosmogony(1946) History (Early life of Georges Lemaitre) Georges Lemaitre served in Belgian Army during world war one as an artillery officer . After war he entered in seminary and in 1923 he became priest . Georges Lemaitre done his studies in U
