Dwarf planet Ceres reveals pyramid-shaped mystery


Image of Pyramid taken by NASA’s Spacecraft DAWN. Do you think it is just a simple mountain or Something else.
OK, this is just too much.

First, NASA’s Dawn probe spotted curiously sparkly bright spots on the surface of Ceres, the dwarf planet that lies in the asteroid belt between Mars and Jupiter.
Beats us, the scientists said.

Now, cameras on the tractor-trailer-size spacecraft have captured a baffling structure rising 3 miles above the planet’s cratered surface.

Conveniently, the thing looks an awful lot like a pyramid.”Intriguing,” the NASA scientists said.

To be fair, the agency offered no suggestion that the towering structure is an offering to some long-lost space emperor or home to our new alien overlords.
And, to be even more fair, it’s probably just a really tall mountain in a solar system filled with wondrous and strange natural phenomena.

But the Dawn mission has done nothing but stoke imaginations since the discovery of mysterious bright spots on the surface of the dwarf planet in February and the beginning of the probe’s orbit in March.

Folks have claimed to have spotted giant alien motherships hovering over the planet, bat-winged spaceships parked on its surface and even evidence of alien cities.

But the mystery only deepened with the most recent batch of images showing even more bright spots alongside the largest one, which NASA said looks to stretch some 6 miles.

Many, of course, insist that the spots look for all the world like brightly lit cities twinkling on the shadowed surface of the distant dwarf planet.

Of course, NASA hasn’t traveled down that road. Scientists, they say, still don’t know what the spots are. Maybe ice. Maybe salt.
“But scientists are considering other options, too,” NASA said coyly.
But #itsaliens, right?

Signs of Alien Life Will Be Found by 2025, NASA’s Chief Scientist Predicts


1920x1080_the-universe-journey-wallpaper-[5]

Here’s the full quote, as delivered by NASA Chief scientist Ellen Stofan at Tuesday’s panel discussion on the Agency’s search for habitable worlds and alien life:

“I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years.

We know where to look. We know how to look,” Stofan added. “In most cases we have the technology, and we’re on a path to implementing it. And so I think we’re definitely on the road.”

Former astronaut John Grunsfeld, associate administrator for NASA’s Science Mission Directorate, echoed Stofan’s assessment. “I think we’re one generation away in our solar system, whether it’s on an icy moon or on Mars, and one generation [away] on a planet around a nearby star.”

Maybe it’s time to start placing bets. Personally, my money’s on Europa – but each of the following “ocean worlds” listed in this infographic from NASA a solid candidate:

The icy eyes of Mars

One thing all solid bodies in the Solar System share in common is craters. Some worlds, like Mercury or the Moon, are covered in them, having no atmosphere to erode them away. Earth has relatively few; our dynamic atmosphere and water circulation wipes them out after a few millennia. And some icy bodies like Saturn’s moon Enceladus or Jupiter’s Europa only have a few because their surfaces are also constantly changing… on a geologic timescale.

Massive Exoplanet Evolved in Extreme 4-Star System


According to a team of astronomers headed by Dr Lewis Roberts from NASA’s Jet Propulsion Laboratory in Pasadena, an extrasolar gas giant called 30 Arietis Bb (30 Ari Bb) is the second known example of a planet residing in a system with four stars.

Artists conception of the 30 Ari star system. In the foreground is the primary star about which the massive exoplanet orbits. The primary’s newly-found binary partner, a red dwarf, can be seen in the upper left and the secondary binary system can be seen to the upper right.

While 30 Ari Bb was known before, it was thought to reside in a system of three stars, not four.

The system, called 30 Ari, is located in the constellation Aries, approximately 136 light-years away.

“Star systems come in myriad forms. There can be single stars, binary stars, triple stars, even quintuple star systems. It’s amazing the way nature puts these things together,” Dr Roberts said.

The planet itself is enormous, with 9.88 times the mass of Jupiter. It orbits its primary star, 30 Ari B, every 335 days. This star has a relatively close partner star, which the planet does not orbit.

The pair, in turn, is locked in a long-distance orbit with another pair of stars about 1,670 AU away.

“It’s highly unlikely that this planet, or any moons that might circle it, could sustain life,” Dr Roberts and his colleagues said.

The first four-star planet, Ph1b, was discovered in the star system Kepler-64 (KIC 4862625) in 2013 by astronomers using data from NASA’s Kepler mission.

The latest discovery, reported in the Astronomical Journal (arXiv.org preprint), suggests that exoplanets in quadruple star systems might be less rare than once thought.

The similarity between Kepler-64 and 30 Ari is that both systems are quadruples consisting of two relatively close pairs that are widely separated.

In fact, recent studies have shown that this type of star systems is itself more common than previously believed.

“About 4% of Sun-like stars are in quadruple systems, which is up from previous estimates because observational techniques are steadily improving,” said team member Dr Andrei Tokovinin of the Cerro Tololo Inter-American Observatory in Chile.

The scientists also reported on a triple-star planetary system, HD 2638, which hosts a so-called hot-Jupiter.

This giant planet, named HD 2638b, orbits its primary star tightly, completing one lap every 3 days.

This woman wants to live and die on Mars—and 200,000 others would gladly take her place

Dina was born in Iraq, lives in the US, and may end her life on Mars.

She’s one of 663 people who are still in the running for a place on the first four-person team that Mars One, a Dutch organization launched in 2011, wants to send to the red planet. Candidates have been whittled down from some 200,000 who applied.

In a video made for the Guardian by Stateless Media, Dina (whose last name isn’t given) and two other hopefuls—one from the UK, one from Mozambique—discuss love, sex, and death on Mars.

Dina is 29 now, but she’ll be nearing 40 by the time of the Mars mission’s planned launch in 2024. She could be almost a year older than that when they arrive on Mars, which is up to 300 days’ travel away .
Her days may then be numbered. A group of strategic engineering graduates estimated that the first of the travelers would die in 68 days—though the plan is to live there much longer .

Intimacy is not encouraged, because of the potential risks of childbirth—though in the long term the future of colony would rely on it .

No one will return from the mission. This led, last year, to a prohibition on Muslims joining the mission , issued by the General Authority of Islamic Affairs and Endowment in the United Arab Emirates. It judged the mission to be so inevitably fatal that it is essentially suicide.

In the future, the mission plans to meet its costs, to a large extent, via broadcast rights . The first mission will cost $6 billion, according to estimates, though a subsequent mission—a plan is already in the pipeline—would be somewhat cheaper.

Planets orbiting Kepler 444 suggest there’s ancient life in the Milky Way


red_star_by_enricoagostoni

NASA’s exoplanet hunting Kepler space telescope has encountered a few problems as of late, but there’s still a mountain of data for astronomers to dig through from the last four years. Astronomers analyzing Kepler data recently uncovered something unusual — a solar system about 117 light years away in the direction of Lyra called Kepler-444 with at least five Earth-sized planets. That would be unusual enough, but this planetary system is also extraordinarily ancient at roughly 11.2 billion years.

Astronomers are intrigued by this discovery for several reasons. First, that’s a lot of small rocky planets. Kepler detects alien worlds by the transit method. It watches distant suns for slight dips in brightness that indicate a planet has passed between it and the telescope. These events can be used to calculate the characteristics of the planet, but it works best for larger worlds (super Earths and gas giants). Spotting five planets between the size of Mercury and Venus (basically a little smaller than Earth) is unusual.

Kepler-444

Artistic Depiction of Kepler 444 with its Star

The age of Kepler-444 is also something to note. At 11.2 billion years old, the planets orbiting this star were already older than Earth is now when our sun ignited 4.5 billion years ago. The universe itself is only 13.8 billion or so years old, making Kepler-444 one of the oldest stars in the Milky Way. It would have been from the first generation of stars that dotted the sky. Kepler-444 is still very sun-like because it’s 25% smaller and cooler. That means it burns through its nuclear fuel more slowly.

Finding small rocky planets that are billions of years older than Earth suggests that advanced life may have existed in the universe for a very long time. Life on Earth might be very new by comparison. Just think, planets similar to Earth were forming more than 7 billion years before Earth formed, and some of them could have supported life. If other first-generation stars like Kepler-444 have planets, uncountable civilizations could have come into being eons before the first single-cell life appeared on Earth.

The planets orbiting Kepler-444 themselves are not able to support life as we know it. All five planets are packed very close to the parent star with orbits closer than that of Mercury in our solar system. With solar years less than 10 Earth days, they definitely stood out in the Kepler data. The surfaces of these worlds have been baked by the intense heat, reducing any organic material to cinders.

Kepler-444 isn’t a bastion of alien life, but it improves our understanding of planetary formation and points us in a new direction. Astronomers are anxious to find other ancient stars with rocky planets in hopes they might prove more hospitable to life. What if there was still something alive on one of these ancient worlds? That might sound like science fiction right now, but maybe it won’t always be — there’s still a lot of data from Kepler, and future telescopes will improve our ability to spy distant exoplanets.

Mars has gas, and Curiosity finds organic matter — fuzzy signs of life?

It could be a sign, a vague one.

A NASA rover has found the building blocks of life on Mars. They might be the product of past or present life on the Red Planet — or they might not be.

Either way, the samples of organic matter in the atmosphere and in rock show that Mars may at least have once had conditions favorable to hosting life, NASA said in a statement. They also show that the planet is still chemically active.

The Curiosity rover’s tapping into organics in rock is the first find ever of life’s building blocks on Mars’ surface.

Gas blast

The rover has run into pockets of gas on Mars: methane, often used to fire up gas stoves back on Earth.

Organic matter is made up of carbon bonded with other elements, often hydrogen and oxygen. Living things are made up of it, but life is not necessary for it to exist.

Methane is the smallest organic compound, consisting of one carbon and four hydrogen atoms.

On our planet, methane is a fossil fuel, but it can also rise out of rotting sewage or fly through the air in flatulence.

In other words, it usually comes from something living, or something that was once alive.

No life found

That could be the case on Mars, too, NASA said in a statement this week.

But the space agency carefully points out that methane can also come from inanimate sources as well.

“There are many possible sources, biological or non-biological, such as interaction of water and rock,” said Sushil Atreya, a scientist on the Curiosity team.

At this point, NASA doesn’t know if microbes are behind the gas or just minerals.

Researchers used Curiosity’s instruments a dozen times to get a breath of methane, and four of those times, it peaked at a level 10 times higher than usual.

They believe it may have been puffed up from the ground like little burps.

Organic rock

Curiosity also found organic matter while drilling into stone.

“This first confirmation of organic carbon in a rock on Mars holds much promise,” said scientist Roger Summons, who works on the rover team.
