Many people assume that astronomers “see” exoplanets directly through their telescopes, perhaps akin to the Earth as a pale blue dot sitting alongside a distant star. The reality is much stranger: in most cases, all that is seen is a single, stationary pin-point of light – the star itself. Yet by measuring the brightness of that speck of light, astronomers may see a tiny repeated dimming, as though the star is winking at us, indicating the transit of an exoplanet in front of the star, blocking a fraction of the light. But just from that faint light, we are able to find out a lot about the exoplanet.
With the help of simple methods and powerful telescopes, astronomers may infer that the star is wobbling back and forth, as it is tugged by the gravity of an exoplanet. From the depth of the “wink” and the amplitude of the “wobble”, the size and mass respectively of the unseen exoplanet can be determined. This can give us its density and surface gravity which in turn tell us what the exoplanet may be made of.
NASA EXOPLANET BULLCRAP
Exoplanets are nothing more than twinkling stars – PATHETIC!
About 97% of all the known exoplanets, have been discovered by indirect techniques of detection, mainly by radial velocity measurements and transit monitoring techniques. The following methods have proved successful for discovering a new planet or confirming an already discovered planet: 
Light variations due to relativistic beaming
Light variations due to ellipsoidal variations
Looks like NASA accidentally panned over one of the lights in their underwater swimming pool. ROFL!
In scenes when Damon makes contact with the crew, he types and reads messages back in real time, when there would likely be a delay of many minutes to get messages to Mars and back.
Nor does the movie allude to the dangers of radiation in space, and the risk of cancer that would likely stalk the Mars pioneers if they made it back to Earth.
Not to mention that NASA is still working on the machinery to rocket humans to Mars. The US space agency has begun testing the Orion deep space capsule, but its first manned flight test may not be until 2023.
“I think the reality is that even if all those technologies were ready — if the Orion was magically ready tomorrow — we would be a no-go for launch because the human body is not yet ready for us to go to Mars,” said Camille Alleyne of the International Space Station program science office.
But space policy expert John Logsdon said he expects the story will inspire young people to keep working on ways to get there.
“I think the bottom line of both the book and the movie is yes, it is worth doing,” he said.
THE LATEST LIVE FROM NASA!!!!
Astronomers have spotted the closest thing yet to the first true ‘Earth twin’ — a small planet orbiting the bright star Kepler 452, at a distance where liquid water could exist.
“It is the first terrestrial planet in the habitable zone around a star very similar to the Sun,” says Douglas Caldwell, an astronomer at the SETI Institute in Mountain View, California.
The alien world is 60% larger than Earth and orbits its star at a distance similar to that between Earth and the Sun. The star itself lies 430 parsecs from Earth, in the constellation Cygnus. It is slightly brighter than the Sun, making its planet a better Earth analogue than planets announced last year and in January, both of which orbited dim, cool stars.
NASA announced the planet, dubbed Kepler-452b, on 23 July, as part of the latest harvest of worlds spotted by its Kepler spacecraft. From 2009 to 2013, Kepler stared at a small patch of sky looking for slight decreases in starlight that signalled a planet moving, or transiting, across the face of a star. The spacecraft has discovered more than 1,000 confirmed planets, including Kepler-452b, and more than 4,660 candidates.
I set a course just east of Lyra
And northwest of Pegasus
Flew into the light of Deneb
Sailed across the Milky Way
On my ship, the ‘Rocinante’
Wheeling through the galaxies,
Headed for the heart of Cygnus
Headlong into mystery
The x-ray is her siren song
My ship cannot resist her long
Nearer to my deadly goal
Until the Black Hole,
Apollo was astonished
Dionysus thought me mad
But they heard my story further
And they wondered and were sad
Looking down from Olympus
On a world of doubt and fear
It’s surface splintered
Into sorry hemispheres
They sat a while in silence
Then they turned at last to me
(We will call you Cygnus)
(The God of balance you shall be)
We can walk our road together
If our goals are all the same
We can run alone and free
If we pursue a different aim
Let the truth of love be lighted
Let the love of truth shine clear sensibility
Armed with sense and liberty
With the heart and mind united
In a single, perfect, sphere
HAHAHAHAHAHAHAHAHAHA! NASA openly laughing in the face of anyone stupid enough to believe their childish bullcrap. They even stuck a profile of Disney’s Pluto on Pluto!
NASA Loses Contact With New Horizons; Pluto Spacecraft Enters ‘Safe Mode’
Ten days before NASA ’s New Horizons spacecraft was due to make its closest approach to Pluto, the space agency reports that at 1:54 PM EDT on the afternoon of July 4th local U.S. time, it lost contact with the $700 million unmanned flyby mission for more than an hour and twenty minutes. Controllers were able to regain a signal from the probe via NASA’s Deep Space Network at 3:15 PM. EDT, but as a result, the spacecraft’s systems have entered safe mode until mission engineers can diagnose the problem.
During the time that it was out of contact with Earth, the probe’s “autonomous autopilot on board the spacecraft recognized a problem and – as it’s programmed to do in such a situation – switched from the main to the backup computer,” NASA reports in a statement issued via Johns Hopkins University’s Applied Physics Lab, which manages the mission for the space agency. NASA says “the autopilot placed the spacecraft in “safe mode,” and commanded the backup computer to reinitiate communication with Earth.”
No, I’m not making this up. Those liars, idiots, and nutjobs of NASA want to use nuclear weapons to defend us from asteroids. Never mind the fact that everything they say is a lie, whether about space, the earth, asteroids, and even nuclear weapons. The only protection we need is from the liars at NASA. Let’s call this Operation Nutjob, as it will fit in nicely with their past operations:
Operation Highjump – Lunatics lose half their fleet trying to get over the ice wall
Operation Deepfreeze – Lunatics freeze to death journeying past the ice wall
Operation Fishbowl – Lunatics try to blow a hole in the firmament
Nasa prepares for real-life Armageddon: Agency could launch nuclear bombs into space to defend Earth from asteroids
- Nasa has teamed up with the National Nuclear Security Administration
- Using a nuclear weapons to blow up asteroids may work particularly well on medium-sized asteroids and comets between 164 and 492 feet
- But experts say resulting rock fragments may make the situation worse
