In the world of science fiction, when aliens attack the Earth, they often go after another rocky sphere. That would be the moon, our planet’s only natural satellite. Although there are exactly zero humans currently residing on the moon, zero pieces of essential equipment or instruments (although let’s be real, those lunar go-karts are pretty dope) situated on its surface or its orbit, and no concrete sense of whether it possesses any valuable resources, the moon is essential to our species’ survival on this planet. If hostile aliens were to blow it to bits or cause some serious damage to it, human would be in serious trouble — even if we managed to successfully repel an extraterrestrial threat.

The moon has played a key role in shaping the way natural processes of Earth, and it continues to do so today. The moon is thought to have been formed just a mere 30 million years after the Earth (which itself is 4.53 billion years old). Since then, the moon’s single greatest (and most obvious) effect on the Earth has been the mediation of the ebb and flow of tides on the planet’s bodies of water.

Scientist believe that in the infancy of this relationship, the moon’s distance from Earth was half of what it is today — and this resulted in much more extreme tides. These tides drove heat from the equator to the poles, leading to ice ages. These glacial shifts spurred more rapid migratory patterns in various species, resulting in a more diverse array of life around the globe. In fact, because of how important water is to molecular processes in primitive life and organic materials, tide shifts may have acted as a kind of natural way for those chemical reactions to get rid of or acquire water in the formation of basic structures like nucleic acids. In other words, tides may have jumpstarted or encouraged the evolution of life on Earth.

Because it's gone forever.

Okay, that’s a pretty cool history lesson, but what about today? What exactly would be the biggest impact on our lives today if the moon disappeared or had a chunk ripped out from itself?”

“We’d lose the normal rhythm of tides,” says Noah Petro, a research scientist at NASA Goddard Space Flight Center who works with the Lunar Reconnaissance Orbiter. He tells Inverse we’d probably lose the large tides we’re used to on a day-to-day basis, and instead experience “smaller tides, caused by the Earth’s rotation with the sun.”

The most noticeable effect this would have is that we’d see oceans around the world level off, to a certain extent. While initially that might save coastal communities from having to deal with potential floods during high-tide, it would also mean they would lose the benefits of low tide. That would wreak havoc on clams, which would have a cascading effect on underwater ecosystems as well as the beachside food shacks worldwide.

Furthermore, the moon plays a significant role in distorting water around the equator. Without a natural satellite, that water would probably redistribute itself around the poles. This might seem like a good thing for coastal cities by the ocean that are constantly threatened by rising floods. But this is awful for bodies of water inland that are fed by oceans. We might see estuaries — responsible for desalinating water naturally — dry up or become significantly reduced. Rivers and lakes further inland would also shrink by quite a bit.

Unless we manage to make artificial desalination technology viable, we’d see the whole world inundated by water shortages — and that’s already a problem much of the world is currently contending with.

Petro also cites two other significant effects the moon’s vanishing act would have on Earth. “The moon stabilizes Earth’s orbit,” he says, “so we’d see changes to the climate we’re currently used to.” He points to Mars as an indicator of what we might see. Mars doesn’t have large moons like Earth’s to affect its axial tilt as much, so the red planet is stuck with very long ice ages.

On Earth, there would be a significant amount of long winters, and “a general cooling off,” of the world at first, he says, perhaps followed by a warming. We’d see “wild extremes” that are more drawn out and last much longer than the planet has previously exhibited. Petro emphasizes that these climatic effects would certainly not be felt immediately — they would occur on a scale of 1,000 to 10,000 years. But there is one other effect that humans would have to find solutions to very quickly if the moon were blown up or hit with some sort of explosive force: debris.

A lot of material, he says, would be expelled into Earth’s orbit, and some of it might even push through the atmosphere and strike the surface. If that debris were big enough, we’d basically deal with a catastrophic scenario of falling moon rocks that not even Brian May would be able to fix.

Let’s also not forget the fact that orbital debris is also an increasing threat to the world’s satellite currently zipping around the globe. Some of those instruments are extremely important to communications systems used by governments and militaries. If aliens fired a bunch of missiles at the moon, we can basically kiss those satellites goodbye. Hopefully we have a few landlines still lying around as a backup.

“Fortunately, we don’t expect the destruction of the moon to happen,” Petro added, laughing.

A NASA scientist has warned that comets arcing through our Solar System could pose more of a threat (or at least as much of one) than asteroids that are constantly in the headlines as being a potential danger to life on Earth as we know it. And there are several reasons why a comet headed on a collision course with our planet could be far more devastating, perhaps even producing an extinction level event not seen in tens of millions of years.

Live Science reported recently that the warning has gone out that not only is Earth totally unprepared for defending itself against an imminent asteroid strike but that comets on a collision trajectory would also likely pose greater risks to the planet. Such a collision might even result in the extinction of a majority, if not all, of the major living organisms on Earth.

NASA scientist Dr. Joseph Nuth of the Goddard Space Flight Center in Greenbelt, Maryland, during a news conference at the annual fall meeting of the American Geophysical Union (AGU) held in San Francisco where he made a presentation on the asteroid deflection capabilities and possibilities currently available, suggested that scientists and policymakers should broaden the scope of the potential dangers to Earth hurtling through the Solar System. He said that comets, though often dismissed, are an ever-present threat and it was time that they, too, be considered when taking measures to protect against extra-planetary-generated impacts.

“Comets have largely been ignored by people that are interested in defending the planet.”

The primary reason comets aren’t given their due, Nuth said, was the perception that little can be done to stop comets. This is in part due to the difficulty astronomers have in spotting and tracking them.

“A comet comes out of nowhere, pretty much,” Nuth said during his presentation a few hours prior to the press conference.

In fact, the last near-miss comet, Siding Spring, buzzed Mars, coming to within 87,000 miles (140,000 kilometers) of our neighboring planet. And earlier this year, an asteroid or comet slammed into Jupiter, an event caught on camera by an amateur astronomer, according to CBS News.

But Earth has to worry about comets the size of Shoemaker-Levy 9, the comet that disintegrated in the atmosphere of Jupiter in 1994 after it was caught by the gas giant’s gravitational field. Scientists estimated, according to a Shoemaker-Levy 9 question and answer webpage set up by Stephen F. Austin State University in Texas, the size of the original comet from the fragments that fell to Jupiter as being approximately 3 miles (5 kilometers) to 6 miles (10 kilometers) across. (In his presentation, when Nuth spoke of giant asteroids that Earth needed to defend against, he referenced, as was reported by the Inquisitr, the “dinosaur killer” asteroid — or comet — that impacted some 65 million years ago, a space rock estimated to have been at least 6 miles (10 kilometers) wide.)

And scientists and agencies need to worry not only about them being spotted late in their orbits and limiting the response time to mount a defense, but also about size and trajectory and velocity. As Nuth explained, comets generally are larger than the average asteroid. The orbital paths of comets have also been found to be elliptical (as opposed to asteroids, where the orbits of most are roughly like Earth’s), with the comet making its journey from the outer reaches of the Solar System, moving in for direct hits (whereas asteroids usually strike the Earth at various angles). Whereas the asteroids travel at an average speed of 44,700 miles per hour (71,940 kilometers per hour), the long elliptical trips of comets see them pick up speed as they approach the sun. For instance, comet Siding Spring was traveling at 125,000 mph (200,000 kilometers per hour) as it passed Mars.

Greater mass. Greater velocity. Greater potential for a direct collision. According to Nuth, these factors provide for “potentially cataclysmic” consequences. He also pointed out that given that extinction-event-level asteroids and meteors collide with the Earth about every 50-60 million years on average and the last impactor, the “dinosaur killer,” hit roughly 65 million years ago, the planet was due for a catastrophic asteroid or comet strike.

The problem with comets: Dr. Joseph Nuth of NASA says they’re bigger, faster, impact more directly, and could appear virtually out of nowhere.

The problem, as Nuth pointed out at the presentation, was that there was nothing at present the Earth could do about a hazardous object headed for the Earth unless there was at least five years to prepare or launch some type of interception or deflection mission. This was why along with suggesting that measures be taken to defend the planet more effectively, he also had suggested a possible solution at the presentation.

Nuth suggested a two-part defensive strategy which would employ an “observer” and an “interceptor” spacecraft. The former would study potentially hazardous objects to deem the seriousness of the threat. The latter, which could be outfitted with a nuclear weapon, would be used for destroying or deflecting the object.

“It’s really imperative that we reduce that reaction time,” he said at the news conference.

Other methods of deflection presented at the AGU included the suggestion of the use of lasers to target an incoming object, possibly producing gaseous jet eruptions from said object and knocking it from its collision-course trajectory, and the use of a “kinetic impactor,” described as “basically a giant cannonball,” that would act to batter an asteroid — or comet — off its trajectory.
