Wow! Rare Photos Capture 2 Comets Together in Night Sky

Two comets are putting on an amazing night sky show this month and some intrepid photographers have captured rare views of both celestial objects at the same time.

The photos of Comet Pan-STARRS?- which made its closest pass by Earth today (March 5)?- and Comet Lemmon were taken by veteran space photographers in Chile and Australia in late February. At the time, both comets were visible from the Southern Hemisphere, though Comet Pan-STARRS is set to become visible from the Northern Hemisphere later this week.

One of the double-comet photos was taken by Yuri Beletsky, a Magellan Instrument Support Scientist at Las Campanas Observatory located in the Atacama Desert of Chile. Beletsky is an accomplished space photographer and used a Canon 5D Mark II camera with an exposure time of about 30 seconds on Feb. 28 to capture the rare sight of the two comets together.?

"Both comets fit perfectly in the field of view of the camera, although only the Pan-STARRS comet was clearly visible by unaided eye," Beletsky told SPACE.com in an email. "The image turned out to be quite deep (you can see many stars across the field) due to excellent atmospheric transparency and darkness of Chilean night sky, and also due to absence of light pollution."

Comet Pan-STARRS was discovered in June 2011 by astronomers using the Panoramic Survey Telescope & Rapid Response System, or Pan-STARRS telescope, in Hawaii. The comet's official designation is C/2011 L4 (PANSTARRS) and it is making its closest approach to Earth today, coming within 100 million miles (160 million kilometers) to the planet. The comet has brightened considerably in recent days, and could be a dazzling naked-eye sight in the March night sky. [Photos of Comet Pan-STARRS by Stargazers]

Comet Lemmon, or C/2012 F6, was discovered by Alex Gibbs of the Mount Lemmon survey in Arizona in March 2012. It has been gradually getting brighter as it entered the inner solar system and will make its closest approach to the sun on March 24.

Beletsky is not the only stargazer to snap a photo of comets Pan-STARRs and Lemmon together. Patience and some skillful camera positioning also paid off for astrophotographer Justin Tilbrook of Penwortham, South Australia, who captured a? remarkable photo of the two comets on Feb. 17.

In Tilbrook's image, Comet Lemmon appears low above the horizon at the bottom left of the frame, while Comet Pan-STARRS is clearly visible as a bright object with a wispy tail on the right side of the image, near a smudge of light that is the Small Magellanic Cloud (a satellite galaxy of the Milky Way).

"This is the one I've been waiting for," Tilbrook told SPACE.com in an email. "Don't mind saying it was difficult to set this up, a narrow window before sunrise, 4 degrees of hill in the way, limitations with the dome slit and having to mount the camera at the front of the scope at a very odd angle. Took about an hour." He used a Canon 1100D with 18 to 55 zoom lens at 28mm f/4, mounted on a HEQ Pro 5.

So far, Comet Pan-STARRS has been visible from the Southern Hemisphere, but that will change on Thursday (March 7), when the comet enters the Northern Hemisphere night sky.

Apple's Lightning to HDMI adapter opened up, discovered to contain a tiny AirPlay computer

Apple's Lightning to HDMI adapter opened up, discovered to contain a tiny AirPlay computer

The fine folks at Panic were experimenting with video out from iOS -- never we mind why -- and came across an interesting discovery: Apple's Lightning Digital AV adapter, aka HDMI adapter, doesn't seem to pass along a 1080p signal in the traditional manner. Instead, it looks like it's passing along upscaled AirPlay-like video. Intrigued as to how, Cabel Sasser gutted the adapter like a Tauntaun on a cold night to find out, and shared what he discovered on the Panic Blog:

Your eyes don?t deceive you ? that tiny chip says ARM. And the H9TKNNN2GD part number on there points towards RAM ? 2Gb worth.

So it's a tiny computer. More specifically, a tiny, single purpose, hard-lined Apple TV-esque device. That explains the less-than-stellar quality of the output (ugh!), but not why Apple chose to go this way.

For some theories on that, and more on Panic's adapter adventure, including the torn-open guts of the gear, check out the link below.

Violence spreads in Borneo as five Malaysian police killed

LAHAD DATU, Malaysia (Reuters) - Gunmen have killed five policemen in Malaysia's Sabah state where members of an armed faction from the Philippines have been facing off with security forces as they stake an ancient claim to the remote corner of Borneo island.

Police on Friday tried to end the standoff with scores of followers of the sultan of Sulu, a south Philippine region, who occupied a Sabah village in February to press their claim. Two policemen and 12 followers of the sultan were killed.

The killing of the five policemen late on Saturday, in an ambush on police hunting followers of the sultan, will reinforce fears that insecurity is spreading in a region rich in resources that has been of increasing interest to investors.

Malaysia's inspector general of police, Ismail Omar, tried to ease any worries on Sunday, saying the situation was under control.

"I don't want speculation that Sabah is in crisis," Ismail told a news conference in the town of Lahad Datu. "We have our security forces at three places to respond."

The confrontation had threatened to reignite tension between the Philippines and Malaysia. Ties have been periodically frayed by security and migration problems along their sea border.

Economic interests are also at risk.

Oil majors like ConocoPhillips and Shell have poured in large sums to develop oil and gas fields in Sabah. Chinese companies have been investing in hydro-power and coal mining.

Much of Borneo's forest has been cleared, to the horror of indigenous people and environmentalists, and replanted with palm oil. Tens of thousands of migrants have come to Sabah from the Philippines to clear the timber and work the plantations.

For generations Borneo, one of the worlds' biggest islands, was a forbidding expanse of jungle, thinly populated by head-hunting tribesmen, and claimed by Muslim sultans and later European colonialists based in coastal trading towns.

"DRASTIC ACTION"

Colonial Britain and the Netherlands carved up the island in the nineteenth century and Malaysia and Indonesia took their shares upon independence. Britain agreed to independence for the tiny oil-rich sultanate of Brunei on Borneo's west coast.

But under a pre-colonial pact between sultans, Sulu, in what would later become the Philippines, was awarded control of the northern corner of Borneo, in what would later become Malaysia.

A British trading company agreed during colonial times to pay Sulu a nominal lease for Sabah - it now amounts to 5,300 ringgit ($1,700) a year - and the claim of the ancient Sulu sultanate on Sabah was all but forgotten, until February.

Then, about 150 followers of the Sulu sultanate, which has no power but commands respect in the southern Philippines, sailed in and occupied a Sabah village, staking their claim and demanding a renegotiation of Sabah's lease.

Malaysia has said the demands will not be met and has sent in the security forces. Both Malaysia and the Philippines have called on the gunmen to give up and go home.

An increasingly exasperated Malaysian prime minister, Najib Razak, who faces an election in weeks, has promised "drastic action" if the group does not leave.

The trouble looks to be at least partly the result of efforts to forge peace in the southern Philippines, in particular a peace deal signed between the Philippine government and Muslim rebels last October to end a 40 year conflict.

Jamalul Kiram, a former sultan of Sulu and brother of the man Philippine provincial authorities regard as sultan, said the peace deal had handed control of much of Sulu to Moro Islamic Liberation Front (MILF) rebels, ignoring the sultanate.

The sultan loyalists had gone to Malaysia to revive their claim to Sabah as a protest in response to what they saw as the unfair peace deal, he said.

A senior Malaysian defense official said the gunmen in Sabah had links with a Philippine rebel faction leader called Nor Misuari, who also saw no benefit from the pace deal.

"He will surely stir up more trouble," said the Malaysian official, who declined to be identified.
