The first space exploration to study a star up close
If all goes according to plan, starting around 3:30 am Eastern on Saturday, NASA will launch the Parker Probe from Cape Canaveral, Florida. If you’re game to stay up that late, check out the live stream of the launch below (or check back during daylight hours for a replay).
After launch, the probe will make its first pass of the sun in about three months. But it will actually take around seven years to dip down within 4 million miles of the solar surface and get a super-close look at the corona. (The corona extends outward about 5 million miles from the surface.) During those seven years, the Parker Probe will make use of Venus’s gravity to alter its orbit, gradually getting closer and closer to the sun. Continue reading “How to get to the sun?”
There is not enough CO2 remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere
Mars does not retain enough carbon dioxide that could practically be put back into the atmosphere to warm Mars, according to a new NASA-sponsored study. Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities.

One of the nice things NASA does is stream live footage from the International Space Station as it orbits the Earth 16 times a day. It’s pretty calming stuff—until a UFO enters the picture. Then all bets are off.
On July 9, NASA was streaming footage from the ISS when YouTuber Streetcap1 spotted something (aliens? probably aliens) entering the Earth’s atmosphere. But as the object (again, almost 100 percent aliens) nears our planet, the NASA feed cut out. While Streetcap1 points out it could be a meteor, we’ve seen Independence Day. We know what’s up. You can see the video below:
NASA has been accused of a ccover-up of the existence of aliens after its video live feed of the International Space Station (ISS) apparently went off just as a UFO appeared to be entering Earth’s atmosphere.
Curious as to why NASA would cover up such obvious evidence of an impending alien attack, the answers was:
“We have never seen UFOs in the popular sense,” said a NASA spokesperson, after a long, deep sigh. “The feed in question is the High Definition Earth Viewing experiment. Anytime the ISS has a signal, that feed is sending down video.”
But when the High Definition Earth Viewing system loses signal, the video stream goes dark. “The feed is not switched manually,” said the spokesperson. “It’s all done automatically. There’s nobody at a control board.
SpaceX has finally landed its Falcon 9 rocket on a drone ship at sea:
(I recommend that you watch the whole video of this mission) SpaceX’s Falcon 9 rocket launched a cargo spacecraft to the International Space Station, but most important part is the fact that after several failed attempts, SpaceX successfully landed the first stage of the rocket on an ocean barge. All previous SpaceX’s attempts to land the rocket on a floating drone ship crashed.
[Few days ago, Blue Origin successfully launched and landed their rocket. Watch it here]
That triple-solar view isn’t the only weird thing you’d see happen overhead.
Astronomical Journal published the details of the discovery of this triple sun planet. Gizmodo talked with lead author of the paper Jason Eastman of the Harvard-Smithsonian Center for Astrophysics. He sketched out a timeline for what that might look like, both over a few days or thousands of years:
You’d see the primary star about the size of your outstretched, splayed hand (about 40x the apparent size of our Sun). Your year and day would be the same: 3 Earth days, which means half of planet would be in continuous daylight and the other half would be in continuous darkness.
You’d also see two points of light about 2 degrees apart, each as bright as the full moon (KELT-4BC). Those two points would orbit each other every 30 Earth years, and every 4000 years, they’d make a complete orbit in the sky (that is, for 2000 years, they’d rise during the Summer and for 2000 years, they’d rise during the Winter).
Precision? The Webb can detect heat generated by a bumblebee as far away as the Moon.
There is much information about the Universe that is invisible even to the Hubble Space Telescope—and that’s where NASA’s much hyped, two-decades-in-the-making, $8.8 billion-plus James Webb Telescope comes in. The Webb Telescope being built by NASA and its partners is a more direct successor to the Spitzer Telescope rather than the Hubble. In short, the Webb will open up a whole new world of infrared astronomy when it launches in 2018. The telescope will be able to capture images of the very first stars and galaxies, formed only 200 million years after the Big Bang.
The movie shows us what it’s like to live on the International Space Station. Many astronauts report feeling the “overview effect” in space and transformed their minds after seeing Earth from space. It leaves astronauts feeling awestruck and gives them a newfound appreciation for the world as a fragile planet that we share.
Filmed in space and narrated by Jennifer Lawrence, NASA’s hoping we feel that way, too — and possibly inspire us to do more to protect our only home in the solar system. It fittingly comes to theaters on April 29, celebrating Earth Day (April 22).
This color-coded chart traces the trajectories of every orbiter, lander, rover, flyby, and impactor to ever slip the surly bonds of Earth’s orbit and successfully complete its mission—a truly astronomical array of over 100 exploratory instruments in all.
