NASA confirmed Thursday afternoon that its Messenger spacecraft collided into Mercury’s surface at more than 8,000 mph, creating a new crater on the planet.

NOTE : MESSENGER (a backronym of MErcury Surface, Space ENvironment, GEochemistry, and Ranging) was a robotic NASA spacecraft which orbited the planet Mercury.MESSENGER became the second mission after Mariner 10’s 1975 flyby to reach Mercury when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009, prior to entering Mercury’s orbit in March 2011. It was the first spacecraft to orbit Mercury.

“Going out with a bang as it impacts the surface of Mercury, we are celebrating Messenger as more than a successful mission,” John Grunsfeld, associate administrator for NASA’s Science Mission Directorate said. “The Messenger mission will continue to provide scientists with a bonanza of new results as we begin the next phase of this mission — analyzing the exciting data already in the archives, and unraveling the mysteries of Mercury.”

But before Messenger’s years-long mission came an end, NASA released several new photos of Mercury, as taken by the spacecraft. Some of these photos were composite imagery, combining years of data and photos collected by Messenger, according to CNET.

Here’s one of the incredible false-color images recently published by NASA. The different colors signify variations in mineral composition, topography and other factors on Mercury’s surface.

NASA is working with Russia on a new space station


STS-116_spacewalk_1

Astronauts Repairing Space Module

Russia is teaming up with the USA to build ISS 2.0 once the current one’s funding runs out in 2024 — at least according to Russia Today and state news agency TASS. The country’s space agency, Roscosmos threatened in February to use the Russian ISS modules as a platform for a new base of its own after 2024, but now it looks like there will be a followup collaboration.

This time around, both parties are looking for participation from other countries, as well as private industry, and are apparently even eyeing a team-up for potential missions to Mars. Russian news outlets report the announcement came during a news conference Saturday following the launch of a year-long mission (video of the launch and subsequent ISS docking is embedded after the break) to the current International Space Station.

NASA Statement –

We are pleased Roscomos wants to continue full use of the International Space Station through 2024 — a priority of ours — and expressed interest in continuing international cooperation for human space exploration beyond that. The United States is planning to lead a human mission to Mars in the 2030s, and we have advanced that effort farther than at any point in NASA’s history. We welcome international support for this ambitious undertaking. Today we remain focused on full use of our current science laboratory in orbit and research from the exciting one-year mission astronaut Scott Kelly just began, which will help prepare us for longer duration spaceflight.

Chief Komarov, who was there for the US-Russia year-long ISS mission launch, reportedly said: “We have agreed that Roscosmos and NASA will be working together on the program of a future space station.” In addition to building a new ISS, sources say the agency’s partnership also entail working on a joint Mars mission. In the same event, NASA chief Charles Bolden is quoted saying: “Our area of cooperation will be Mars. We are discussing how best to use the resources, the finance, we are setting time frames and distributing efforts in order to avoid duplication.”

So far NASA hasn’t announced or confirmed anything through its official channels. We’ve contacted the agency for comment and will update this post if we hear anything.

Black Hole 12 Billion Times Bigger Than the Sun Discovered


Interstellar-team-and-black-hole

Scientists say they have discovered a black hole so big that it challenges the theory about how they grow.

The scientists were initially reluctant to classify it as a black hole because it was too bright, its luminosity equal to the brightness of 420 trillion suns. Most of the people do not believe black holes to be bright, though they can be. This is particularly so because black holes suck everything inside them but just before that there is tremendous friction which produces a lot of light.

Scientists said this black hole was formed about 900 million years after the Big Bang.

But with measurements indicating it is 12 billion times the size of the Sun, the black hole challenges a widely accepted hypothesis of growth rates.

“Based on previous research, this is the largest black hole found for that period of time,” Dr Fuyan Bian, Research School of Astronomy and Astrophysics, Australian National University (ANU).

“Current theory is for a limit to how fast a black hole can grow, but this black hole is too large for that theory.”

The creation of supermassive black holes remains an open topic of research. However, many scientists have long believed the growth rate of black holes was limited.

Black holes grow, scientific theory suggests, as they absorb mass. However, as mass is absorbed, it will be heated creating radiation pressure, which pushes the mass away from the black hole.

“Basically, you have two forces balanced together which sets up a limit for growth, which is much smaller than what we found,” said Bian.

The black hole was discovered a team of global scientists led by Xue-Bing Wu at Peking University, China, as part of the Sloan Digital Sky Survey, which provided imagery data of 35 percent of the northern hemisphere sky.

The ANU is leading a comparable project, known as SkyMapper, to carry out observations of the Southern Hemisphere sky.

Bian expects more black holes to be observed as the project advances.

U.S. and Russian Astronauts to Spend One Year on the ISS


iss-backlit-wallpapers_32164_1920x1080

In another U.S. and Russian joint mission, American Astronaut Scott Kelly and Russian Cosmonaut Mikhail Kornienko will spend 12 months on the International Space Station starting this March, confirms NASA.

During their one year stay in the ISS, Kelly and Kornienko will perform seven research experiments to aid scientists gather significant knowledge on the biomedical, psychological and medical challenges faced by astronauts in long-term space flight.

Among other things, scientists will study differences in vision, functionality, mental health, metabolic processes and physical performance separately from behavioral changes and motor performance.

Another set of tests will be conducted on Kelly and Astronaut Mark Kelly, Scott Kelly’s twin brother and also an astronaut who will stay on Earth.

“These investigations will provide broader insight into the subtle effects and changes that may occur in spaceflight as compared to Earth by studying two individuals who have the same genetics, but are in different environments for one year,” NASA said in a statement.

Mark Kelly’s experience includes piloting Space Transportation System 108 (Endeavour), STS-124 (Discovery Commander) and STS-134 (Endeavour Commander).

Scott Kelly was a crewman of STS-103 in 1999; STS-118 in 2007 and a 159-day stay on the ISS starting on October 7, 2010.
It’s going to be a strangely extensive space mission since a typical NASA mission to the ISS lasts no more than six months.

ISRO’s Mars Mission team has won the prestigious 2015 Space Pioneer Award in the science and engineering category in recognition of achieving the rare feat in its very first attempt.

The prestigious award given by the National Space Society would be presented to the ISRO’s Mars Orbiter Programme Team during the National Space Society’s 2015 International Space Development Conference to be held in Toronto from May 20-24.

The mission was launched on November 5, 2013 and went into Mars orbit on September 24, 2014.

In a statement, the Society said, this mission has achieved two significant mission firsts. One an Indian spacecraft has gone into orbit around Mars on the very first try (on Sept 24, 2014), which no other country has ever done.

Secondly, the spacecraft is in an elliptical orbit with a high apoapsis (point at which an orbiting object is farthest away from the body it is orbiting), and has a high resolution camera which is taking full-disk color imagery of Mars.

“Very few full disk images have ever been taken in the past, mostly on approach to the planet, as most imaging is done looking straight down in mapping mode. These images will aid planetary scientists,” the statement said.

The Mars Orbiter programme team located in Bangalore is headed by Dr Mylswamy Annadurai.

The Space Pioneer Award consists of a silvery pewter Moon globe cast by the Baker Art Foundry in Placerville, California, from a sculpture originally created by Don Davis, the well-known space and astronomical artist.

New Hubble Telescope Photos Capture One of the Universe’s Most Stunning Formations


In 1995, the Hubble Space Telescope captured what would become one of history’s most enduring images of the universe: The Eagle Nebula’s Pillars of Creation. Now, 20 years later, Hubble has released a collection of brand new, high-definition shots of the iconic formation. 

If you thought the universe was hauntingly beautiful before, wait until you see these.

Behold:

New view of the Pillars of Creation — visible

Comprised of three towers of gas, dust and space matter, structures like this are not altogether uncommon in star-forming regions. But as the Hubble website notes, the Pillars of Creation are some of the most photogenic and mesmerizing examples ever seen.

“The Hubble image of the pillars taken in 1995 is so popular that it has appeared in film and television, on tee-shirts and pillows, and even on postage stamps,” HubbleSite writes.

The telescope used the Wide Field Camera 3 to capture the stunning new images. It sees near-infrared light, visible like and near-ultraviolet radiation, and also has higher resolution and a bigger field of view than the camera that came before it.

This time, Hubble also captured an image taken in infra-red light, which “penetrates much of the obscuring dust and gas and unveils a more unfamiliar view of the pillars,” according to the website. “Here newborn stars, hidden in the visible-light view, can be seen forming within the pillars themselves.”

New view of the Pillars of Creation — infrared

Not everything is happy-go-lucky in Pillars of Creation-land, however. Despite their name, the new shots indicate that the pillars are also being worn down by the very stars they are helping to incubate. “The dust and gas in these pillars is seared by intense radiation from the young stars forming within them, and eroded by strong winds from massive nearby stars,” HubbleSite explains.

Arizona State University’s Paul Scowen, who helped lead Hubble’s first deep dive into the Eagle Nebula, stressed just how incredible our sightings of the Pillars are. “I’m impressed by how transitory these structures are,” he said in a press release. “We have caught these pillars at a very unique and short-lived moment in their evolution.”

Interestingly, environments like the Eagle Nebula and other star-forming regions were instrumental in our own solar system’s development. “What that means is when you look at the environment of the Eagle Nebula or other star-forming regions, you’re looking at exactly the kind of nascent environment that our Sun formed in,” Scowen said.

8 new planets found in ‘Goldilocks zone’, NASA may find Earth’s ‘twin’ very soon

NASA is closer than ever to finding a twin for the Earth, astronomers said today, announcing the discovery of eight new planets that circle in the habitable zones of their stars.

Two of the eight are the most Earth-like of any known planets found so far outside our solar system, astronomers told the 225th meeting of the American Astronomical Society in Seattle, Washington.

The pair are likely to have hard, rocky surfaces in addition to being an orbiting distance from their stars that is neither too hot nor too cold for water and possibly life to exist, astronomers said. The discovery doubles the number of known planets that are close in size to the Earth and believed to be in the so-called “Goldilocks zone” of the stars they orbit.

“We are now closer than we have ever been to finding a twin for the Earth around another star,” said Fergal Mullally of the Kepler Science Office. “These candidates represent the closest analogs to the Earth’s own system found to date.”

The worlds were found with the help of NASA’s planet-hunting Kepler mission, a space telescope which has scoured more than 150,000 stars for planets beyond our solar system since its launch in 2009. The latest trove of candidate planets found by Kepler and announced today was 554, bringing the total potential planets to 4,175.

Scientists have recently verified the existence of the 1,000th planet found by Kepler.

“Three of the newly validated planets are located in their distant suns’ habitable zone, the range of distances from the host star where liquid water might exist on the surface of an orbiting planet,” NASA said in a statement. “Of the three, two are likely made of rock, like Earth.”

While it is intriguing to consider the possibility of life existing on another planet like ours, the two best candidates are so far away that learning more about them presents a big challenge.

This One Picture Will Make You Realize How Big The Universe Actually Is


Milky_Way_Galaxy_Top_View

Milky Way Galaxy (Click Image to Download)

We’ve all heard the universe is a very big place, but this image from Alex Grossman really drives that concept home.

The question: How far has humanity’s influence reached?

The very first thing created by humanity that left our tiny planet wasn’t a satellite or space ship, it was the broadcasts from a world obsession with radio. This image shows how far radio broadcasts will have reached in our galaxy, the Milky Way, by the time that technology is 200 years old. Considering we only started broadcasting in 1880, this map actually represents our reach in 2080.

In the vacuum of space radio waves travel at the speed of light, so our entire influence on the universe has now traveled just 135 light years away from Earth (1 “light year” equals the distance light travels in 1 year). That’s right, the tiny blue dot in the image below is how far every single action by humanity has reached. Feel tiny yet?

Universe-Size-730x730

How does that compare to our furthest traveling spacecraft? The Voyager 1, which is now traveling almost outside the influence of our Sun, is only about 18 light hours away from the Earth. That’s about 97,000 times smaller than the blue dot in these pictures.

Now for the real kicker.

How many galaxies like our Milky Way are in the entire Universe? No one knows the actual figure because we can’t see to the outside edge (if there is one), but the amount we can see in the observable universe is estimated to be… wait for it…

…more than 170 billion galaxies.

There it is. We are really, really, very, amazingly, incredibly, so, small.
