First habitable exoplanet?

First habitable exoplanet? | Good news from the Stars | Scoop.it
"The planetary system around the red dwarf Gliese 581, one of the closest stars to the Sun in the galaxy, has been the subject of several studies aiming to detect the first potentially habitable exoplanet."

A French Astrophysics team concluded that the planet named Gliese 581d can be considered the "first confirmed exoplanet that could support Earth-like life".

But it doesn't mean it looks like Earth at all. See why in the article.

Tyche or not Tyche and G1.9

Tyche or not Tyche and G1.9 | Good news from the Stars | Scoop.it
A few months ago I published here reports of the possible discovery by NASA of a new planet : Tyché. What was confusing was that just a few days before I saw an article about Spanish astronomers claiming the same but naming the object G1.9.

I asked Quora and here's the answer.

Tyché, a hypothetical gas giant planet at the edges of the solar system, might exist but its existence is far from proven. G1.9 is a totally different thing (I removed the article which made the confusion from this topic of course).

Are you a Martian? We all could be, scientists say | Good news from the Stars | Scoop.it
Are we all Martians? According to many planetary scientists, it's conceivable that all life on Earth is descended from organisms that originated on Mars and were carried here aboard meteorites. If that's the case, an instrument being developed by researchers at MIT and Harvard could provide the clinching evidence.

Haven't heard of Voyager in a long time? Well the probe's alive and kicking

Haven't heard of Voyager in a long time? Well the probe's alive and kicking | Good news from the Stars | Scoop.it
"In which direction is the sun's stream of charged particles banking when it nears the edge of the solar system?"

That's an answer not easy to get unless you're there. But more than 33 years after their launches, Voyager 1 and 2 are not only going to remain the only human spacecrafts in that area for decades, they're also fully functional.

How's that for a long-lasting technology?

Great Summary on Stars

Great Summary on Stars | Good news from the Stars | Scoop.it
How do stars form and evolve? Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. The age, distribution, and composition of the stars in a galaxy trace the history, dynamics, and evolution of that galaxy. Moreover, stars are responsible for the manufacture and distribution of heavy elements such as carbon, nitrogen, and oxygen, and their characteristics are intimately tied to the characteristics of the planetary systems that may coalesce about them. Consequently, the study of the birth, life, and death of stars is central to the field of astronomy.

Giant ring of black holes

Giant ring of black holes | Good news from the Stars | Scoop.it
This would not be a good place for space tourism...

"This composite image of Arp 147, a pair of interacting galaxies located about 430 million light years from Earth, shows X-rays from the NASA's Chandra X-ray Observatory (pink) and optical data from the Hubble Space Telescope (red, green, blue) produced by the Space Telescope Science Institute (STScI) in Baltimore, Md."

"The nine X-ray sources scattered around the ring in Arp 147 are so bright that they must be black holes, with masses that are likely ten to twenty times that of the Sun."

Apparently, the collapse (explosion ?) happened some 15 million years ago.

NASA Looks Into Laser-Propelled Rockets As a Safer, Cheaper, and More Efficient Way to Space | Popular Science

NASA Looks Into Laser-Propelled Rockets As a Safer, Cheaper, and More Efficient Way to Space | Popular Science | Good news from the Stars | Scoop.it
Replace controlled explosions by more clever ways ? Looks promising.

"Launching payloads into space is expensive, but high costs aside it’s also a horribly inefficient process. Conventional rockets are almost pure fuel, leaving only a small percentage (usually in the low single digits) of a launch vehicle's total weight available for payload. So NASA's Glenn Research Center in Ohio is looking into a whole new system of payload propulsion that uses lasers or microwaves to launch vehicles into orbit."

NASA + William Shatner: Space Shuttle’s Legacy

Very promotional , yet interesting recap of the 30-years of the Space Shuttle program.

I remember watching John Young commanded STS-1 first Shuttle launch on TV with my grand-parents when I was 10. In spite of Challenger's and Columbia's tragedies, this program was quite something.

Letter from College Students regarding the Future of Human Spaceflight

Letter from College Students regarding the Future of Human Spaceflight | Good news from the Stars | Scoop.it
"We are the ones who will be most affected by the decisions you make today."

Here is what they recommend: a big push to open up space to commercial age and form partnerships between NASA and commercial spaceflight companies. "Everyone wins when NASA partners with the commercial spaceflight industry." or again "Allow NASA to explore the solar system again by embracing commercial spaceflight."

And also a reminder that the youth can make things happen: "As NASA inspired and amazed the world by landing humans on the surface of the Moon in the late 1960s, the average age in NASA's Mission Control was only about twenty-eight."

Fossils of algae-like beings in meteorites reported by astrobiologist Richard Hoover in Journal of Cosmology

Hoover claims that the lack of nitrogen in the samples, which is essential for life on Earth, indicates they are "the remains of extraterrestrial life forms that grew on the parent bodies of the meteorites when liquid water was present, long before the meteorites entered the Earth's atmosphere."

Tyche, Giant Hidden Planet, May Exist In Our Solar System

Tyche, Giant Hidden Planet, May Exist In Our Solar System | Good news from the Stars | Scoop.it
"We may have lost Pluto, but it looks like we might be getting Tyche. Scientists may soon be able to prove the existence of the gas giant, which could be four times the size of Jupiter, according to astrophysicists John Matese and Daniel Whitmire from the University of Louisiana at Lafayette."

For those following this topic, this apparently is the new name of the G1.9 Brown Dwarf Star that Spanish Astronomers claimed the discovery of last summer (see post here: http://t.co/shYC8Fk ).

And it's apparently not a new discovery (NASA P/R again ?) since this article dated last April already mentioned the whole Nemesis/Tyche story: http://bit.ly/cVXSOs

Per Wikipedia, "The use of the name "Tyche" for the planet may also be a reference to an earlier theory of the Solar System's structure that involved the Sun having a dim companion named Nemesis as it was proposed as a cause for mass-extinctions on Earth. Tyche was the name of the sister of Nemesis." http://bit.ly/es1eE5
