Pastel-colored Jupiter dazzles in gorgeous Hubble telescope photo

The Hubble Space Telescope captured this unique panchromatic image of Jupiter on Aug. 25, 2020. The photo combines Hubble observations in near-infrared, visible and ultraviolet light.

 It's like somebody put Jupiter under a blacklight. 

A new photo by the Hubble Space Telescope shows the solar system's largest planet in surprising pastel hues.

The image, captured on Aug. 25, combines data in ultraviolet, visible and near-infrared light to give researchers a new look at Jupiter, one that could reveal insights about the gas giant's thick atmosphere.

"In this photo, the parts of Jupiter’s atmosphere that are at higher altitude, especially over the poles, look red as a result of atmospheric particles absorbing ultraviolet light," Hubble team members wrote in a description of the photo, which was released on Thursday (Sept. 17). "Conversely, the blue-hued areas represent the ultraviolet light being reflected off the planet."

The white storm in the upper left portion of the image, which first boiled up on Aug. 18, "is grabbing the attention of scientists in this multiwavelength view," Hubble team members wrote. "The 'clumps' trailing the white plume appear to be absorbing ultraviolet light, similar to the center of the Great Red Spot, and Red Spot Jr. directly below it. This provides researchers with more evidence that this storm may last longer on Jupiter than most storms."

Hubble, a joint project of NASA and the European Space Agency, launched to Earth orbit aboard the space shuttle Discovery in April 1990. Scientists soon realized that the big scope had a flaw in its primary mirror, which spacewalking astronauts fixed in December 1993. 

Astronauts maintained and upgraded Hubble on four additional servicing missions after that, the last of which occurred in 2009. As the new Jupiter photo shows, the telescope is still giving astronomers and the public amazing views of the cosmos, three decades after its launch.

Mars rock layers swirl in gorgeous crater photo

A southern portion of Mars' Holden Crater, as imaged by the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

A sliver of Martian geological history takes center stage in a striking photo of a Red Planet crater.
The image, captured by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter (MRO), shows dramatically swirling layers of rock in the 87-mile-wide (140 kilometers) Holden Crater.
"Much of Mars is covered by sand and dust, but in some places stacks of sedimentary layers are visible," NASA officials wrote Monday (June 8) in a description of the photo. 
"In this image, exquisite layering is revealed emerging from the sand in southern Holden Crater," they added. "Sequences like these offer a window into Mars' complicated geologic history."

That history includes a stretch long ago when the planet's surface was likely capable of supporting Earth-like life. As work by robotic explorers such as MRO and NASA's Curiosity rover has shown, ancient Mars sported rivers, lakes and, some scientists believe, a huge ocean that covered most of the planet's northern hemisphere.
Everything changed about 4 billion years ago, when Mars lost its global magnetic field. The planet's once-thick atmosphere was then exposed to stripping by the charged particles of the solar wind, and Mars was transformed into the cold, dry world we know today. 
Holden Crater was once a potential landing site for Curiosity, by the way. But NASA ultimately selected the 96-mile-wide (154 km) Gale Crater for the six-wheeled robot's rovings.
Holden Crater lies about 26 degrees south of the Martian equator, whereas Gale Crater is at just 5 degrees south.

Apollo 13: Enhanced photos show ill-fated moon mission in unprecedented detail

On April 11, 1970, Apollo 13, which was the third moon-landing mission of NASA, launched from Kennedy Space Center in Florida, U.S. It was supported by astronauts Jim Lovell (R), Jack Swigert (C) and Fred Haise (L). However, things took an unfortunate turn and the mission was aborted due to a rupture and later explosion of an oxygen tank. The Apollo aircraft circled the moon without landing, and returned on Earth safely on April 17.


Lovell practices flag deployment on Feb. 4.

The Apollo 13 crew travel from the suiting station to a van that will transport them to the rocket site on April 11.

The severely damaged Apollo 13 Service Module (SM) is photographed from the lunar module. An entire panel on the SM was blown away by the explosion of an oxygen tank.

A Navy helicopter hovers over the Apollo 13 capsule in the Pacific Ocean as frogmen release the astronauts. The USS Iwo Jima recovery vessel waits nearby.

The three astronauts are seen after their rescue.
Life aboard Nasa’s ill-fated Apollo 13 mission has been revealed in unprecedented detail thanks to a series of enhanced images originally taken 50 years ago.
The spacecraft was supposed to become Nasa’s third to land on the moon in 1970 before an explosion jeopardised the lives of the three astronauts on board and forced them to make a dramatic journey home.
Fifty years on from the mission, imaging specialist Andy Saunders has managed to produce the clearest pictures yet from the craft, using low-quality 16mm film shot by the crew.
Mr Saunders used a technique called “stacking” to bring together multiple frames on top of each other to improve the detail of the images.
In one picture, Commander Jim Lovell can be seen selecting some music on a tape player as the crew prepares for their return to Earth.
Mr Saunders said it was striking in the footage how calm the crew appeared, even though they faced an extremely challenging journey home.
“This perhaps belies their true feelings as we know that, in reality, the crew doubted if they would make it home alive,” he told the BBC
The enhanced images were released as two of the astronauts involved in the near-disastrous mission said they still viewed the aborted trip as a success.
Mr Lovell described Apollo 13’s return to Earth as a “miraculous recovery”, while Fred Haise said it was a “great mission” despite its difficulties.
Mr Haise said the journey showed “what can be done if people use their minds and a little ingenuity”.
The astronauts also insisted they were not superstitious about the trip and said they both used the number 13 in their email addresses.
Jack Swigert, the craft’s third crew member, died in 1982 after being diagnosed with cancer.

Apollo 13 astronaut hails ‘miraculous recovery’ 50 years after rescue

The severely damaged Apollo 13 service module after separation from the lunar module/command module

Two of the astronauts who successfully returned to Earth after a near-disastrous Apollo 13 mission still consider the aborted trip a success 50 years after the world watched their ordeal with bated breath on television.
Jim Lovell and Fred Haise are still able to talk about the drama which spawned a Hollywood movie although the third crew member, Jack Swigert, died in 1982.
Although they never made it to the moon after their oxygen tank ruptured on April 13, Mr Lovell and Mr Haise insist they are not superstitious and both use 13 in their email addresses.
“I’m still alive. As long as I can keep breathing, I’m good,” mission commander Mr Lovell, now 92, said from his Lake Forest, Illinois, home.
A half-century later, Apollo 13 is still considered Mission Control’s finest hour.
Mr Lovell calls it “a miraculous recovery.”
Gene Kranz never said “failure is not an option”

Mr Haise, like so many others, regards it as Nasa’s most successful failure.
“It was a great mission,” Mr Haise, 86, said.
It showed “what can be done if people use their minds and a little ingenuity”.
As the lunar module pilot, Mr Haise would have become the sixth man to walk on the moon, following Mr Lovell onto the dusty grey surface.
The oxygen tank explosion robbed them of the moon landing, which would have been Nasa’s third, nine months after Apollo 11′s Neil Armstrong and Buzz Aldrin took humanity’s first footsteps on the moon.
Now the Covid-19 pandemic has robbed them of their anniversary celebrations.
Festivities are on hold, including at Kennedy Space Centre in Florida, where the mission began on April 11, 1970, a Saturday just like this year.
Apollo 13 commander James A. Lovell Jr., left, opens the astronauts televised news conference at the Manned Spacecraft Centre, Houston, by saying “I’m not a superstitious man” alluding to the number 13 and the trouble that befell the flight. With Lovell are his fellow crew members, command module pilot John Swigert, centre, and lunar module pilot Fred Haise
That will not stop Mr Haise, who still lives in Houston, from marking what he calls “boom day” next Monday, as he does every April 13.
Mr Lovell, Mr Haise and Mr Swigert, a last-minute replacement, were almost to the moon when they heard a bang and felt a shudder.
One of two oxygen tanks had burst in the spacecraft’s service module.
The tense words that followed are the stuff of space, and movie, fame.
“OK, Houston, we’ve had a problem here,” radioed Mr Swigert, the command module pilot.
“This is Houston. Say again, please.”
“Houston, we’ve had a problem,” Mr Lovell cut in.
Mr Lovell reported a sudden voltage drop in one of the two main electrical circuits.
Within seconds, Houston’s Mission Control saw pressure readings for the damaged oxygen tank plunge to zero.
The blast also knocked out two electrical power-generating fuel cells and damaged the third.
As Mr Lovell peered out the window and saw oxygen escaping into the black void, he knew his moon landing was also slipping away.

Safety at last as the command module carrying the Apollo 13 crew parachutes to a splashdown in the Pacific Ocean

He shoved all emotions aside.
“Not landing on the moon or dying in space are two different things,” Mr Lovell explained, “and so we forgot about landing on the moon.
“This was one of survival. How do we get home?”
The astronauts were 200,000 miles from Earth.
Getting back alive would require calm, skill and, yes, luck.
“The explosion could not have happened at a better time,” Mr Lovell said.
Much earlier, he said, and the astronauts wouldn’t have had enough electrical power to make it around the moon and slingshot back to Earth for a splashdown.
Crowds watch a television screen in New York’s Grand Central Station waiting for the safe arrival of the Apollo 13 astronauts in the Pacific Ocean

A blast in lunar orbit or, worse still, while Mr Lovell and Mr Haise were on the surface, “that would be the end of it”.
“I think we had some divine help in this flight,” Mr Lovell said.
The aborted mission went from being so humdrum that none of the major TV networks broadcast the astronauts’ show-and-tell minutes before the explosion, to a life-and-death drama gripping the entire world.
As flight director Gene Kranz and his team in Houston raced to come up with a rescue plan, the astronauts kept their cool.
It was Mr Lovell’s fourth spaceflight, his second towards the moon, and the first and only one for Mr Haise and Mr Swigert.
Dark thoughts “always raced through our minds, but silently. We didn’t talk about that”, Mr Lovell said.
Added Mr Haise: “We never hit the point where there was nothing left to do. So, no, we never got to a point where we said, ‘Well, we’re going to die.’”
The White House, less confident, demanded odds.
Jim Lovell and Fred Haise never made it to the moon

Mr Kranz refused, leaving it to others to put the crew’s chances at 50-50.
In his mind, there was no doubt, no room for failure — only success.
“Basically that was the name of the game: I’m going to get them home. My team’s going to get them home. We will get them home,” Mr Kranz recalled.
For the record, Mr Kranz never uttered “failure is not an option”.
The line is pure Hollywood, created for the 1995 movie Apollo 13 starring Ed Harris as Mr Kranz and Tom Hanks as Mr Lovell.
The flight controllers went into crisis mode.
They immediately ordered the command module Odyssey shut down to conserve what little power remained, and the astronauts to move into the lunar module Aquarius, now a lifeboat.

One of the low points, Mr Lovell said, was realising they would be cramped together in the lander.
“It was designed for two people for two days. We were three people for four days.”
The carbon dioxide overload, from breathing, threatened to kill them.
Engineers scrambled to figure out how to convert the square air-purifying canisters in the dead capsule into round ones that would fit in their temporary home.
Their outside-the-box, seat-of-the-pants solution, using spacecraft scraps, worked.
But it was so damp and cold that the astronauts could not sleep.

Condensation covered the walls and windows, and the temperature was close to freezing.
Dehydrated and feverish, Mr Haise had the roughest time during the six-day ordeal.
Despite the sky-high stress, Mr Haise recalls no cross words among the three test pilots.
Even Mr Swigert fit in, despite joining the crew a scant three days before liftoff.
He replaced command module pilot Ken Mattingly, who with his crewmates had been exposed to German measles, but unlike them did not have immunity.
Rumours swirled that the astronauts had poison pills tucked away in case of a hopeless situation.

Mr Lovell dispelled that notion on page one of his 1994 autobiography, Lost Moon, the basis for the Apollo 13 film.
Splashdown day finally arrived April 17 1970 — with no guarantees.
The astronauts managed to power up their command module, avoiding short circuits but creating a rainfall inside as the spacecraft decelerated in the atmosphere.
The communication blackout lasted 1 1/2 minutes longer than normal. Controllers grew alarmed.
Finally, three billowing parachutes appeared above the Pacific.
It was only then, Mr Lovell said, that “we knew that we had it made.”
The astronauts had no idea how much their cosmic cliffhanger impacted the world until they reached Honolulu.
President Richard Nixon was there to greet them.
“We never dreamed a billion people were following us on television and radio, and reading about us in banner headlines of every newspaper published,” Mr Lovell noted in a Nasa history.
The tank explosion later was linked to damage caused by electrical overheating in ground tests.
Apollo 13 “showed teamwork, camaraderie and what Nasa was really made of”, said Columbia University’s Mike Massimino, a former shuttle astronaut.
In the decades since, Mr Lovell and his wife, Marilyn, of nearly 68 years have discussed the what-ifs and might-have-beens.
“The outcome of everything is, naturally, that he’s alive,” she said, “and that we’ve had all these years”.
