From intergalactic neutrinos and invisible brains, to the creation of miniature human “organoids”, 2013 was an remarkable year for scientific discovery. Here are some of the biggest scientific breakthroughs, innovations and advances of 2013.
Voyager I Leaves the Solar System
Escaping the solar system is no mean feat. For 36 years, NASA’s Voyager 1 spacecraft has putting distance between itself and the Sun at speeds approaching 11 miles per second. At a pace like that, scientists knew Voyager was approaching the fringes of the heliosphere that surrounds and defines our solar neighborhood – but when would it break that barrier? When would it make the leap to interstellar space? After months of uncertainty, NASA finally made the news official this September. "Voyager 1 is the first human-made object to make it into interstellar space" said Don Gurnett, lead author of the paper announcing Voyager’s departure; “we’re actually out there.”
The Milky Way is Brimming with Habitable Worlds
Planet-hunting scientists announced in November that 22% of sunlike stars in the Milky Way are orbited by potentially habitable, Earth-size worlds. This remarkable finding suggests there could be as many as two-billion planets in our galaxy suitable for life — and that the nearest such planet may be only 12 light-years away. Is Earth 2.0 out there? With figures like that, it’s hard to imagine otherwise. Who knows – with all the Kepler data we’ve got to sift through, there’s a chance we’ve already found it.
Curiosity Confirms Mars Was Once Capable of Harboring Life
In March, NASA scientists released perhaps the most compelling evidence to date that the Red Planet was once capable of harboring life. Earlier this year, Curiosity drilled some samples out of a sedimentary rock near an old river bed in Gale Crater. This geological area used to feature a series of stream channels, leaving behind finely grained bedrock indicative of previously wet conditions. Using the rover’s onboard instrumentation, NASA scientists analyzed these samples to detect some of the critical elements required for life, including sulfur, nitrogen, hydrogen, oxygen, phosphorus, and carbon. The rover is currently on a trek to its primary scientific target – a three-mile-high peak at the center of Gale Crater named Mount Sharp – where it will attempt to further reinforce its findings.
Researchers Detect Neutrinos from Another Galaxy
By drilling a 1.5 mile hole deep into an Antarctic glacier, physicists working at the IceCube South Pole Observatory this year captured 28 neutrinos, those mysterious and extremely powerful subatomic particles that can pass straight through solid matter. And here’s the real kicker: the particles likely originated from beyond our solar system – and possibly even our galaxy. ”This is a landmark discovery,” said Alexander Kusenko, a UCLA astroparticle physicist who was not involved in the investigation, “possibly a Nobel Prize in the making.”
NASA Discovers “A Previously Unknown Surprise Circling Earth”
NASA’s recently deployed Van Allen probes — a pair of robotic spacecraft launched in August 2012 to investigate Earth’s eponymous pair of radiation belts — turned out out some very unexpected findings in February, when they spotted an ephemeral third ring of radiation, previously unknown to science, surrounding our planet.
Human Cloning Becomes a Reality
A scientific milestone 17 years in the making, researchers announced in May that they had derived stem cells from cloned human embryos.The controversial technology could lead to new treatments for diseases like Parkinson’s and diabetes — while bringing us one step closer to human reproductive cloning.
Giant “Pandoravirus” Could Redefine Life as we Know it
Scientists in July announced the discovery of a pair of viruses that defy classification. Bigger and more genetically complex than any viral genus known to science, these so-called “pandoraviruses” could reignite a longstanding debate over the classification of life itself.
Brain-to-Brain Interfaces Have Arrived
Back in February, researchers announced that they had successfully established an electronic link between the brains of two rats, and demonstrated that signals from the mind of one could help the second solve basic puzzles in real time — even when those animals were separated by thousands of miles. A few months later, a similar connection was established between the brain of a human and a rat. Just one month later, researchers published the results of the first successful human-to-human brain interface. The age of the mind-meld, it seems, is near at hand.
There is Life at the End of the World
There is life in Lake Whillans. For millions of years, the small body of liquid water has lurked hundreds of meters below Antarctica’s Ross Ice Shelf, sealed off from the outside world and the scientists who would explore its subglacial depths. Earlier this year, a team of researchers led by Montana State University glaciologist John Priscu successfully bored a tunnel to Whillans and encountered life, making Priscu and his colleagues the first people in history to discover living organisms in the alien lakes at the bottom of the world.
Doctors Cure HIV in a Baby Born With the Disease
In a monumental first for medicine, doctors announced in March that a baby had been cured of an HIV infection. Dr. Deborah Persaud, who presented the child’s case at the 20th annual Conference on Retroviruses and Opportunistic Infection, called it “definitely a game-changer.”
Newly Discovered Skulls Could Prune Humans’ Evolutionary Tree
An incredibly well-preserved, 1.8-million-year-old skull from Dmanisi, Georgia suggests the evolutionary tree of the genus Homo may have fewer branches than previously believed. In a report published in October, a team led by Georgian anthropologist David Lordkipanidze writes that it is “the world’s first completely preserved hominid skull.” And what a skull it is. When considered alongside four other skulls discovered nearby, it suggests that the earliest known members of the Homo genus (H. habilis, H.rudolfensis and H. erectus) may not have been distinct, coexisting species, at all. Instead, they may have been part of a single, evolving lineage that eventually gave rise to modern humans.
Neuroscientists Turn Brains Invisible
Gaze upon the stunning effects of CLARITY, a new technique that enables scientists to turn brain matter and other tissues completely transparent. It’s been hailed as one of the most important advances for neuroanatomy in decades, and it’s not hard to see why.
This year, a man-made machine, originating from the planet Earth, left our solar system and entered interstellar space for the first time… ever… since the beginning of TIME! That is some hardcore business! It truly should be the #1 story of 2013!!!

Photoset with 13 notes
If you haven’t heard of Comet ISON yet, do some research. Our view of the comet from Earth was blocked by the sun from June through early August due to our orbit, but we’ve recently been able to have a direct line of sight again and we now have a new image from the Hubble Space Telescope.
The official released image is the second one from the Hubble site (linked above), I’ve then noted where the top image would fit into the bottom image. However, the top image is from the Hubble Legacy Archive, which is a joint project of the Space Telescope Science Institute (STScI), the Space Telescope European Coordinating Facility (ST-ECF), and the Canadian Astronomy Data Centre (CADC).
You can access the interactive image here. Zoom out or drag the image down to get to the comet, then by darkening the image (button in top left) you will eventually reveal this odd, symmetric three object shot of the “comet.”
This is strange. Why would NASA & the Hubble site release the bottom image and not discuss the bizarre reality of what lies within it? If the top image represents some natural phenomenon, then why isn’t it being discussed? Also, what are the chances that a natural phenomenon could produce this symmetric pattern that in no way whatsoever resembles any idea of what a comet should look like?
Bitches don’t know ‘bout my space program
This man is so supremely badass, you don’t even KNOW!

Ok, so the reality of Earth’s orbit around the sun is WAY more complex than I ever knew!!!

Trailer for amazing IMAX film showcasing the glorious photography from the Cassini missions to Saturn. Absolutely stunning!
This is the Moon.
But imagine for a second that the Moon switched places with other planets. This is what you would see (subject to staying alive, of course):
