|
|
The Voyager 1 and Voyager 2 probes — which launched in 1977 and are now traveling through interstellar space — may be complicating scientists' understanding of our solar system's structure.
|
|
To put this in perspective, Voyager 1 and Voyager 2, the only spacecraft to make it to interstellar space, are currently around 13 billion miles away from Earth.
|
|
They were designed to be planetary explorers, which meant they weren't outfitted with many of the instruments physicists would need to get a deep understanding of interstellar space.
|
|
The closest it came to Earth was 20.5 million miles (33 million km), and with its speed and extreme angle of entry, the object headed back towards interstellar space.
|
|
Perhaps Voyager 2 is now getting close, too, though one Princeton scientist who uses Voyager data, Jamie Rankin, stressed to Gizmodo that Voyager 2 hasn't yet reached interstellar space.

|
|
Now, they say the data shows that a "so-called jet" of material expanded as fast as the speed of light, heading away from the event and into interstellar space.
|
|
The particles range from single-digit centimeters to tens of centimeters in length, and some of them are slow-moving while others are quickly making their way through interstellar space.
|
|
The second benefit is that it gives spacecraft autonomy from earth (at least in terms of navigation) which makes deep space or interstellar space flight at least one step closer.

|
|
Rather than humans, robots have boldly gone where no one has gone before, digging into the Martian soil, flying by Pluto, landing on comets, and even venturing slowly into interstellar space.
|
|
"It is perhaps more likely that [ancient aliens] origin be local, than that an extraterrestrial species crossed interstellar space and deposited [signs of their existence] here," Wright wrote in his paper.
|
|
This time the passage into interstellar space is yielding a different set of readings, with new clues to how the sun affects space in the far reaches of the solar system.
|
|
Mission controllers actually turned off Voyager's camera soon after the pale blue dot image was taken, shutting its eye on the solar system as it sped away from us toward interstellar space.
|
|
Their most likely result was that the asteroid has been in the Solar System for most of its 4.5-billion-year history, but was captured from interstellar space by the Sun's gravity.

|
|
Over the past four decades, it has been used in two dozen deep space missions, including sending the Voyager craft into interstellar space, doing a flyby of Pluto, and powering rovers on Mars.
|
|
That would also significantly change their estimate for how far it could travel before falling apart -- though as I said, I doubt any functional craft would leave its sail deployed in interstellar space.
|
|

|
|
At the same time, the Breakthrough Initiative is flirting with the idea of sending a nanocraft just a few centimeters in size through interstellar space to our nearest neighbor, the Alpha Centauri star system.
|
|
The edge of interstellar space is also a rapidly changing environment, and the Sun's activity had declined in the six years between the two transits, which surely influenced the conditions experienced by both probes.
|
|
Five years ago, Voyager 1 reached the boundary where the heliosphere gives way to interstellar space, a region as novel to us — and potentially relevant — as the Pacific was to Europeans 500 years ago.
|

Of course, many parts of the Voyager craft still work despite their age — they've been sending reliable telemetry back since launch, including the memorable data in 2012 indicating that Voyager 1 had entered interstellar space.
|
|
The twin probes are now speeding through a region known as the "bow shock," where the plasma of interstellar space flows around the heliosphere, much like water flowing around the bow of a moving ship.
|
|
Subsequent encounters with large planets like Jupiter can toss these cosmic icebergs willy-nilly toward their parent stars or even outward into interstellar space, as evidenced by the intrusions of the comets Oumuamua and Borisov.
|
|
NASA's Voyager 21977 spent the better part of the last 22 years making its way through the heliosphere to become the second human-made object in history to enter interstellar space, the government agency announced Monday.
|
|
Some of those differences might be the result of its evolution as Oumuamua wandered through interstellar space, said Karen Meech of the University of Hawaii, leader of the team, including Dr. Micheli, that discovered the comet.

|
"If active regions of interstellar space, like the Orion Nebula, form lots of small objects as well as massive stars, it could mean there are many more planet-size objects in the universe than previously thought," Space.

According to a hyped new paper from astronomers Fathi Namouni and Helen Morais, this asteroid with its contrary orbit may not be native to our Solar System at all—it may have been captured from interstellar space.
|
|
Scientists also believe that they might have spotted early precursors to what form anomalous cosmic rays, observed by the Voyager 2 space probe, and which might help form the boundary between our solar system and interstellar space.
|
|
If it's not indicative of a hydrogen wall at the boundary of the Sun's influence and interstellar space, then astronomers must furnish an alternative explanation for why this ultraviolet light is observed so far from the Sun.
|
|
The Voyager 230 spacecraft is now in interstellar space, NASA announced on Monday, making it the second human-made machine to cross a boundary that divides our solar system from the rest of the Milky Way galaxy.
|
|
Its bizarre features led astronomers to conclude that it was a cosmic interloper: a giant chunk of rock that was formed in another star system and blasted on a journey through interstellar space billions of years ago.
|
|
Researchers will also need far more data points before being able to definitively understand the structure of the heliosphere, and there is talk of sending a spacecraft purposefully out to interstellar space to fill in the gaps.
|
|
Voyager 1 and Voyager 2 were to use the gravity of the outer planets to slingshot from Jupiter to Saturn, and to Uranus and Neptune, and then beyond the edge of the sun's domain into interstellar space.
|
|
"This is a very exciting time again in Voyager's 41-year journey, so far, of exploring the planets and now the heliosphere and entering interstellar space," Ed Stone, Voyager project scientist based at Caltech, told a news briefing.
|
|
Prof Tim Schmidt, a chemist at the University of New South Wales, Sydney and co-author of the study, said that the windscreen of a future spaceship travelling through interstellar space might be expected to get a sticky coating.
|
|
But so far, only a single spacecraft has made it to interstellar space: Voyager 1, launched in 1977, is currently speeding through the void at a blistering 40,000 miles per hour and covering about 325 million miles per year.
|
|
"Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.
|
|
Dante Lauretta, the principal investigator of Osiris-Rex, said he was particularly interested in gleaning information about organic molecules like amino acids, the building blocks of proteins found on Earth that are also known to exist in interstellar space.
|
|
While the Voyagers, speeding away at more than 34,000 miles per hour, are now in interstellar space, they are still considered to be within the solar system, because they have not yet slipped the grip of the sun's gravity.
|
|
Planets have been discovered in such systems , but just how long they can remain in their orbits before gravitational interactions send them crashing into one of their host stars, or careening out into interstellar space, remains a topic of considerable debate.
|
|
Even if we had the technology for interstellar space travel, we still wouldn't be able to see most of the observable universe because we're actually limited to only being able to go to a hundredth billionth of a percent of it.

NASA's new "power management plan" is intended to keep the Voyager probes working such that scientific data can continue to be collected at the heliopause, the boundary between the solar wind (particles released by the Sun's corona) and interstellar space.
|
|
However, it is not moving quite as fast as the Voyager 1 and Voyager 2 spacecraft that have now both entered interstellar space, so it is unclear whether New Horizons will make a similar crossing before its power runs out.
|
|
Or here&aposs where aliens might come in: Rather than stars, the researchers say that some of these disappearing red objects — those that only appear once in one image — could be lasers that aliens use to communicate across interstellar space.
|
|
In 1980, NASA noticed that Pioneer 10 and Pioneer 11 were slowing down through interstellar space, veering off their expected trajectories—an event that's now called the "Pioneer anomaly," and has been attributed to thermal forces pushing the spacecraft backward.
|
|
During the collision, many stars will be thrown out into interstellar space, and the two galaxies' central supermassive black holes will be unable to resist each other's allure, producing strong gravitational waves as they get closer together, and eventually merging into one.
|
|
The idea that hardy microorganisms can survive long durations through interstellar space may not be as outlandish as it seems, though Loeb admits it's a stretch:It's not clear whether life would survive the journey under freezing temperatures and bombardment by cosmic rays.
|
|
It's fascinating to think that scientists in 1977, working with calculation systems less sophisticated than a modern electronic car key fob, built spacecraft that are still functioning 40 years later, still sending back telemetry from (in Voyager 1's case) interstellar space.
|
|
In a paper presented at the Aeronautics and Astronautics Association of France's Space Propulsion conference this week, a team of German physicists announced SpaceDrive, a research program exploring exotic propulsion mechanisms that they hope will one day make interstellar space travel a reality.
|
|
A space probe specifically designed to study interstellar space would be packed with enough instruments and power to study the universe beyond the sun's heliosphere in detail, far beyond the distance where the useful lives of the Voyager spacecraft come to an end.
|
|
"The high velocity indicates not only that the object likely originated from outside our solar system, but also that it will leave and head back to interstellar space," Davide Farnocchia, who studies near-Earth objects at NASA, said in a press release.
|
|
"In a historical sense, the old idea that the solar wind will just be gradually whittled away as you go further into interstellar space is simply not true," said Don Gurnett, author of one of the studies at the University of Iowa.
|
|
If one thing's clear, it's that Enceladus is shaping up to be a more tantalizing target than ever—and that the Voyager 1 probe, which is still sending back data and making discoveries from the edge of interstellar space, was well worth the investment.
|
|
This is the status of the trailblazing space agency that landed on the Moon in 1969, operates multiple probes on Mars, and has three spacecraft currently hurtling toward or through interstellar space (Voyagers 1 and 23 and New Horizons, in case you were wondering).
|
|
"What we did was take the properties of the meteor and take the velocity at the time of impact and extrapolate whether it was bound to the sun or not," said Loeb, adding that the data pointed to the object originating from interstellar space, according to CNN.

Why it matters: Voyager 2, which joins its twin Voyager 1 in crossing the heliopause (the boundary between the hot solar wind and cold, interstellar space), will provide scientists with crucial observations about the kinds of particles and forces the spacecraft encounters, such as cosmic rays.
|

WASHINGTON (Reuters) - Voyager 13, a NASA probe launched in 1977 and designed for just a five-year mission, has become only the second human-made object to enter interstellar space as it continues its marathon trek billions of miles (km) from Earth, scientists said on Monday.
|
|
Unlike Voyager 1, which is now in interstellar space and would as such potentially be an object of interest to a passing extraterrestrial, it seems a bit of a stretch to think that an intelligence would come all the way here just to stop at the moon.

"This idea nicely explains the high density of these objects drifting in interstellar space, and it shows that we should be finding up to hundreds of these objects with upcoming surveys coming online next year," Gregory Laughlin, an author of the study, said in a statement.
|
|
The two missions will continue studying the region in interstellar space, NASA reports:"I think we're all happy and relieved that the Voyager probes have both operated long enough to make it past this milestone," Suzanne Dodd, Voyager project manager at NASA's Jet Propulsion Laboratory, said in the release.

Since at least Aristotle, the idea that life must've started on Earth was more or less taken for granted in the scientific community, until Wickramasinghe proposed that some dust in interstellar space contained carbon, which would make it organic—a theory he would later prove to be correct.
|
|
Unlike Oumuamua, the cigar-shaped rock that caused a sensation when it cruised through the inner solar system and right back out toward interstellar space last winter, however, this asteroid has taken up permanent residence among us, according to a new study published Monday in Monthly Notices of the Royal Astronomical Society: Letters.
|

Our own solar system tosses the odd object into interstellar space, but the bulk of these objects are comets that form far from Earth, and are only very loosely bound by the Sun's gravity; every once in a while, an Oort Cloud comet jostles free, embarking on its new life as a celestial orphan.
|
|
Micheli's team is theorizing that small dust grains, which that typically litter the surface of comets, eroded during the course of 'Oumuamua's epic journey through interstellar space (we have no idea how old this object is, so who knows how long it's been careening through the Milky Way, which formed 13.5 billion years ago).
|
|
The idea that Fast Radio Bursts are produced by advanced alien civilizations in order to drive spacecraft through interstellar space sounds like something a UFO conspiracy site might cook up—but it's actually the serious suggestion of a new paper published by Avi Loeb and Manasvi Lingam from the Harvard-Smithsonian Center for Astrophysics.
|
|
Interstellar space has enough of the greasy, likely toxic carbon substance that UNSW professor and study co-author Tim Schmidt says it might accumulate on any theoretical future interstellar craft, the Guardian reported:The Australian-Turkish team discovered more than expected: 10 billion trillion trillion tonnes of gloop, or enough for 40 trillion trillion trillion packs of butter.
|
|
Astronomers from Caltech have for the first time identified a chiral molecule—organic molecules that have mirror-image versions of themselves—in interstellar space, a finding that may have implications for one of the nagging sub-mysteries of how the whole life-on-Earth thing worked out in the first place, and how it might work out on other planets.

Scientists can use TNOs to inform questions such as "where Neptune formed and how fast it got to its current location, if the early solar system had another giant planet that got kicked out to interstellar space, how much matter was initially in the solar system, and where the solar system was born in the MIlky Way, among others," he said.
