Earth’s magnetic field is one of the most mysterious features of our planet. It is also essential to life as we know it, ensuring that our atmosphere is not stripped away by solar wind and shielding life on Earth from harmful radiation. For some time, scientists have theorized that it is the result of a dynamo action in our core, where the liquid outer core revolves around the solid inner core and in the opposite direction of the Earth’s rotation.
Since the beginning of the Space Age, humans have relied on chemical rockets to get into space.
What if our Solar System had another generation of planets that formed before, or alongside, the planets we have today? A new study published in Nature Communications on April 17th 2018 presents evidence that says that’s what happened.
At 6:51 EDT on Wednesday, April 18th, a SpaceX Falcon 9 rocket blasted off from Florida’s Cape Canaveral. It was carrying NASA’s TESS: the Transiting Exoplanet Survey Satellite.
When Elon Musk of SpaceX tweets something interesting, it generates a wave of excitement. So when he tweeted recently that SpaceX might be working on a way to retrieve upper stages of their rockets, it set off a chain of intrigued responses. SpaceX will try to bring rocket upper stage back from orbital velocity using a giant party balloon — Elon Musk (@elonmusk) April 15, 2018 SpaceX has been retrieving and reusing their lower stages for some time now, and it’s lowered the cost of launching payloads into space

How to Listen to the Background Hum of Gravitational Waves From all the Black Holes Colliding into Each Other
The first-ever detection of gravitational waves (which took place in September of 2015 ) triggered a revolution in astronomy.
One of the defining characteristics of the modern era of space exploration is the way the public and private aerospace companies (colloquially referred to as the NewSpace industry) and are taking part like never before. Thanks to cheaper launch services and the development of small satellites that can be built using off-the-shelf electronics (aka.
Are you ready for a luxury hotel in space? We all knew it was coming, even though it seems impossibly futuristic. But this time it’s not just science fiction; somebody actually has a plan

As a species, we humans tend to take it for granted that we are the only ones that live in sedentary communities, use tools, and alter our landscape to meet our needs. It is also a foregone conclusion that in the history of planet Earth, humans are the only species to develop machinery, automation, electricity, and mass communications – the hallmarks of industrial civilization. But what if another industrial civilization existed on Earth millions of years ago?
The European Southern Observatory (ESO) has released a stunning collection of images of the circumstellar discs that surround young stars.
Pluto’s Charon Gets Mountains Named After Sci-Fi Authors Octavia Butler and Arthur C. Clarke, as Well as Many Others From History and Legend. I…
In 2015, the New Horizons mission made history by being the first spacecraft to conduct a flyby of Pluto . In addition to revealing things about the planet’s atmosphere, its geology and system of moons, the probe also provided the first clear images of the surface of Pluto and its largest moon, Charon
The Moon and Mars will probably be the first places in the Solar System that humanity will try to live after leaving the safety and security of Earth.
Framed by stars reflected by water, a kayaker leans back to take in the grandeur of the night sky.

The full title is — get ready for this — Wonders of the Night Sky You Must See Before You Die: The Guide to Extraordinary Curiosities of Our Universe
In February of 2016 , scientists working for the Laser Interferometer Gravitational-Wave Observatory (LIGO) made history when they announced the first-ever detection of gravitational waves . Not only did this discovery confirm a century-old prediction made by Einstein’s Theory of General Relativity , it also confirmed the existence of stellar binary black holes – which merged to produce the signal in the first place
In September of 2016 , Elon Musk announced the latest addition to the SpaceX rocket family. Known then as the Interplanetary Transport System (ITS) – now know as the Big Falcon Rocket (BFR) – this massive launch vehicle is central to Musk’s vision of sending astronauts and colonists to Mars someday
On Monday, April 2 the 14th Commercial Resupply Mission to the International Space Station blasted off Cape Canaveral, Florida. It was carrying a Dragon spacecraft filled with cargo for the astronauts on board the station. The rocket was a re-used Falcon 9 rocket, as was the Dragon capsule; both had sent payloads to ISS before.
