Chandra Observatory: 15 Years of Glorious Pictures

Human eyes don't know half of what they're missing. But the Chandra Observatory, with its x-ray vision, gives us a stunning peek.

You’ll never see the universe as beautifully as the Chandra Observatory can see it. That’s because Chandra—which is celebrating its 15th anniversary in high-Earth orbit—sees in x-ray frequencies and you don’t. It’s a pity, actually that we’re blind in that bandwidth, because so much of the cosmos makes itself known there. Signals coming from planets, comets, supernovas, from the dark matter in the vast spaces between galaxies, all emit x-ray energy. The portraits they paint, with false color added to make them visible to our eyes, are more than static snapshots. They are, instead, pictures of processes: of matter spinning down the eternal drain of the black hole at the center of our galaxy; of galaxies colliding and merging; of the cool gas swirling at the center of the Andromeda galaxy.

Chandra records all of these cosmic processes—bits of history really, since at their great distances many of them played out in the remote past. In its own short life, it has crossed many boundaries in terrestrial history too. The satellite was lofted by the shuttle Columbia in 1999—a ship that was destined for catastrophe just four years later. It left Earth at a time when the World Trade Towers stood; when Barack Obama was an Illinois State Senator, one year away from losing his bid for a seat in the U.S. House of Representatives; when no one had ever heard of an iPhone. That doesn’t seem like much in a universe whose chapters play out in epochs, not mere years. But for a fragile machine from a fragile planet, 15 long years of exploratory work aren’t bad—especially when the post cards it sends home are so improbably dazzling. —Jeffrey Kluger

45 Years Later: Remembering the First Moon Landing

The mission that made space history

+ READ ARTICLE

Correction: The original version of this article incorrectly described which Apollo 11 crew members walked on the moon.

On July 16, 1969, a small group of astronauts took one small step for man, and one giant leap for mankind.

It’s been 45 years since Buzz Aldrin and Neil Armstrong became the first people to walk on the moon, leaving those back on Earth to stare at their television screens in awe. The men spent two hours collecting lunar rocks to bring back home to Earth to study.

To commemorate the milestone, the Slooh Space Camera will broadcast live footage from the moon on Sunday, July 20, at 8:30 E.T.

In a photo taken from the International Space Station, smoke blankets a large swath of the western United States

Wildfires across the Pacific Northwest have been blazing since Monday and have scorched large areas of forest as a result of hot, dry weather in Oregon and Washington. A total of 25 large, uncontained wildfires have burned hundreds of thousands of acres, with the single largest affected region in eastern Oregon’s Malheur County where about 369,000 acres of land has been burned. Incredibly, you can see smoke rising above the region from outer space. Reid Wiseman, an astronaut on the International Space Station, posted this photo on his Twitter feed.

Apollo 11′s Rarely-Seen Outtakes

For the 45th Anniversary of the moon landing, TIME searched through NASA's archives for these rarely seen images

After 45 years, you’d think there is no picture of the historic Apollo 11 moon landing that hasn’t been seen a thousand times—but you’d be wrong. Like all travelers, Neil Armstrong, Buzz Aldrin and Michael Collins shot a whole lot of frames, and not all of them were keepers. NASA did keep every one of them, of course. Here a few of that are rarely published—mixed with some of the iconic ones that capture best just how extraordinary that long-ago mission was.

45 Years Later: 5 GIFs of NASA’s First Moon Landing

On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first two people to land on the lunar surface, while their third crew member, Michael Collins, continued to orbit around the moon. Armstrong and Aldrin arrived in the Lunar Module (LM) Eagle, one of three parts of the Apollo 11 spacecraft which also included a Command Module (CM) Columbia and a Command Service Module (CSM) to support Columbia. Approximately six and half hours after a rocky landing, Armstrong and Aldrin exited the LM and set foot on the moon to begin their Extra Vehicular Activities (EVA), with Armstrong uttering his now famous words, “That’s one small step for man, one giant leap for mankind.”

In addition to performing several experiments and collecting samples from the lunar surface, the two meticulously photographed every stage of the EVA with specially designed Hasselblad cameras (one of which was actually left on the moon to help lighten the load on the LM as they returned to Columbia).

All of the images taken by Aldrin and Armstrong were scanned and archived, and are available to the public through NASA’s Apollo Lunar Surface Journal. Below, in honor of the 45th anniversary of the moon landing, TIME has assembled 5 GIFs from Aldrin, Armstrong, and Collins’ images showing in detail some of the historic moments captured by the Apollo 11 crew.

    In this series of three images, Buzz Aldrin photographs the lunar surface before and after making a foot print on it. He had taken his camera off it its RCU bracket and shot these pictures holding the camera in his gloved hands. This 16mm movie camera mounted in his LM window captured Aldrin on film taking these pictures.

  • Buzz Aldrin Sets Up the EASEP

    In this series of images, Armstrong captures Aldrin setting up the EASEP (Early Apollo Surface Experiments Package). Aldrin has the LRRR (Laser Ranging Retro Reflector) in his right hand, and the seismometer package in his left hand. As of December 2010, the retroreflectors were still being used in conjunction with a dedicated facility at the MacDondald Observatory in Texas.

United Arab Emirates Says It Will Go To Mars By 2021

A bold announcement by the United Arab Emirates is more than just an idle boast

The big news out of the Middle East this week is mostly about war and other kinds of tribulation, as it was last week and probably will for weeks to come. War and tribulation, that is, plus a mission to Mars.

According to a report by Reuters, the United Arab Emirates announced it would be creating a space agency by 2021 and sending an umanned probe to the Red Planet—something only the U.S., the USSR/Russian Federation and the European Space Agency have done with any success, while the British, Japanese and Chinese have tried and failed. The jury is still out on an Indian probe, which is currently en route.

So can they do it, or is this just some crazy stunt the UAE hopes nobody will remember when the time comes? The answer: it’s not necessarily crazy. True, the country has no aerospace industry, but a government-backed group based in the Persian Gulf country bought nearly a third of Richard Branson’s Virgin Galactic, a private space tourism company. Moreover, says John Logsdon, a space policy expert and professor emeritus at George Washington University, “The UAE has already been active in space with communications satellites and Earth observation satellites.”

They’ve done this, he says, by purchasing both satellites and launch services from other countries, and they’d almost certainly put together a Mars probe the same way. “Most of the technical work and the launch would be contracted out,” he speculates, “but some of the components could be developed internally.” If that happened, and if UAE space agency engineers were in charge of mission control, he says, “they could appropriately claim that this mission was their own.”

Given the UAE’s deep pockets, it’s certainly possible that the country could pull off such a project, which would bring a new kind of prestige to the region. The Arab world did invent algebra and enjoyed a golden age of science for centuries leading up to the Medieval period and many Arabs dream of the return to that kind of scientific ascendancy. Recent, eye-catching projects—including the successful construction of the world’s tallest building and the world’s largest indoor ski resort—hint at inventive potential.

A Mars mission would obviously be a bit more ambitious, but in the end, it’s really just rocket science, which isn’t as complicated as we sometimes tend to think. Still, it’s one thing to say you’re going to do something like this and quite another to do it. After all, in 1969, NASA was similarly talking about our own manned mission to Mars—with astronauts aboard—in what was then the near future. It could be done, said Wernher von Braun, the rocket engineer behind that year’s successful Moon landing, by 1982.

But it never happened, and who knows if it ever will? The UAE, aided by expertise from other countries, can certainly get a probe to Mars by 2021, in theory.

Whether they’ll actually do it is whole different story.

Now You Can 3D-Print Your Own Stellar Nebula

A new study makes it possible for you to hold one of astronomy's great mysteries in your hands—and understand it better too

+ READ ARTICLE

People alive in 1841 understood the Eta Carinae nebula better than we do. They were the ones who were actually around to watch when an enormous star weighing about 130 times as much as our sun erupted more than 7,500 light years from Earth. Maybe if modern astronomers had been on the scene they could have figured out what caused the blast—and specifically why the vast cloud of dispersing matter that makes up the nebula assumed its signature peanut shape.

Still, the good thing about those modern astronomers is that when they put their minds to something, it’s never too late to get some answers. An international team of researchers has just announced that they have done just that, publishing a new study in the Monthly Notices of the Royal Astronomical Society that may at last unravel the Eta Carinae mystery.

The investigators did their work with the help of the European Southern Observatory’s Very Large Telescope (VLT), conducting elaborate cross-sectional observations of Eta Carinae. These allowed them not only to develop a solid theory about how the star blew, but to create a 3D-printed model of the two-lobed space cloud that came from it.

The model is not much to look at—two irregularly shaped balls of plastic that resemble extracted molars as much as anything else. Still, NASA has made the program necessary for printing your own version of Eta Carinae publicly available. Whether you think it’s display-worthy or not, the model tells a complex story.

The star at the center of the Eta Carinae nebula is actually two stars—a binary pair in perpetual orbit around each other. That had been known for a while, but how—or if—they worked together to shape the nebula was never clear. The international team now believes that the eruption occurred when the smaller star—which measures about 30 solar masses—was at the closest point in its orbit to the larger one. It does not appear that a collision triggered the explosion. That seems to have happened on its own, with the blast beginning at one of the poles of the 130-solar-mass star and propagating across its entire body to the other pole.

But the close approach of the smaller star does seem to have had a powerful influence on shaping the eruptive cloud that resulted—and that star had a lot of material to work with. The larger star, which still exists, is now thought to weigh in at just 90 solar masses; the missing material—about 40 times the mass of our sun—is what we see when we look at the huge cosmic peanut.

Why does any of this matter? Well, it doesn’t, if you take “matter” to mean influencing the well-being of the human species responsible for the finding. But if you mean making that species smarter, explaining to it how some of the universe’s most extraordinary and violently beautiful formations came to be, then it matters indeed—and quite a lot, in fact.

Astronaut Alexander Gerst tweeted this amazing picture of the above-earth view of a supermoon early Monday, when the moon was still behind the horizon.

Gerst is a German astronaut aboard the International Space Station and among many astronauts using the social media site to share incredible pictures of the view from space. Gerst often uses the hashtag #bluedot, a nod to the iconic image of Earth taken from Saturn. And earlier in July, NASA astronaut Reid Wiseman tweeted above-earth images of Super Typhoon Neoguri. Three astronauts recently spoke to TIME about life above the earth, read their comments in this week’s issue.
