A 2015 documentary on the history of space, the current progress of space exploration, and where we might go in the future.
If you have around an hour to spare, and a space itch to scratch, this is an awesome documentary to watch! It has very good scientific support, fantastic HD visuals, and exciting narration. It really opens your eyes to how much we’ve discovered only recently, and also how much we still don’t know. Great documentary!
Beautiful! Would like to visit all of these places someday <3

Over the past week I’ve been compiling a short list of online resources I often use when I’m doing anything space-related online, whether it be writing summaries of news updates or trying to understand some complicated science topic. Hope these are useful!
On getting up-to-date news:
ScienceDaily
Space.com
Science Mag
On understanding scientific topics:
Crash Course
Khan Academy
Space Exploratorium
Of course, there are many resources out there, but these are the ones I use most often.
Bad news, everyone: Trappist-1 may not be the extraterrestrial paradise we thought it would be. On March 29, 2017, a new study was released from the Konkoly Observatory in Hungary that analyzed photometric data on Trappist-1 which was collected by NASA’s K2 mission.
The study suggested that the host star of the Trappist-1 system produces too many powerful solar flares to allow its planets to host and sustain life. Data pointed out 42 high-energy flares that occurred over an 80-day period, 5 of which were “multi-peaked” which means they gave off multiple bursts of energy in one instance. The average time between these flares was 28 hours.
To provide a comparison to understand the magnitude of the solar flares -- the strongest flare on Trappist-1 is equivalent in release of energy to our own Carrington Event of 1859, which would destroy global communications if it happened today. During the Event, the flare sent powerful electrical surges through telegraph lines and produced tropical aurorae so bright, they woke up Rocky Mountain gold miners in the middle of the night because they thought it was morning.
Now, some people might say, “But Earth has managed to survive powerful solar flares in the past. Why can’t Trappist-1 do the same?”
Well, there may be a few reasons why Trappist-1 may no longer be the place to sustain life:
1) Our wonderful Earth has in place a magnetic field that protects us from the worst effects of our host star’s stellar magnetic outbursts, but it is not yet known whether or not the Trappist-1 planets have this same defensive capability.
2) Both the frequency and magnitude of Trappist-1′s solar flares may prohibit its planets from even recovering from previous flares. According to this study done a year ago, it would take 30,000 years for a planet’s atmosphere to recover from just one of a high-intensity flare. Solar flares are occurring every 28 hours on Trappist-1. Logic, then, points out that there is a very small chance of life being possible on any of Trappist-1′s planets.
3) Trappist-1′s planets are very, very close to their Sun -- much closer than we are to our own. This means that the near-constant flaring would likely destroy any chance of stability in the planets’ atmospheres, unless (on the small chance) they somehow have incredibly powerful magnetospheres.
This is definitely disappointing news. I think many people (myself included) had a lot of hope riding on Trappist-1 for the possibility of sustaining life and being a true sister solar system to our own.
But not all hope is lost! There’s still a lot that we can’t confirm about this mysterious and volatile solar system. Scientists are relying on the launch of the James Webb Space Telescope to probe Trappist-1 and give us a more detailed look on what’s going on in that side of the universe. The telescope will launch in 2018, so don’t give up on Trappist-1 just yet! A lot can happen in one year.
Beautiful photo! This reminds me of the time my family and I went to Yellowstone National Park around four years ago. We arrived at the park around midnight and were treated to the clearest star-filled night sky we had ever seen. It was stunning - the stars stretched from one horizon to the next, and there was no end to them. It made me feel very small in the grand scope of the universe, and just how much we miss out when we become accustomed to city lights and the urban sprawl. Makes me want to go camping in some remote place again.

While news of Trappist-1′s potentially inhospitable environment made its way through the news feeds, a new discovery emerged to make up for it: an existing atmosphere on exoplanet GJ1132b.
Located 39 light years away (just around the corner in galactic terms), the exoplanet is similar to Earth in size and mass, and is in close-orbit to its star: a dim red dwarf just slightly cooler and smaller than our own Sun. It was discovered in 2015, but it’s only now that scientists have been able to take a closer look at its composition.
While the distance between GJ and its host star is more similar to the one between Venus and our Sun, therefore most likely rendering the exoplanet incapable of hosting life due to extreme surface temperatures of up to 370 degrees Celsius/700 degrees Fahrenheit, the most important aspect to focus on is the discovery is the atmosphere that exists on GJ.
Using advanced technology that picks out biochemical signatures such as those of oxygen, methane, and hydrogen, scientists have identified a thick atmosphere of either steam or methane surrounding GJ. While this is not a certain indicator of life, it is an crucial step in increasing our knowledge of potentially habitable alien planets out there.
It is definitely interesting to see that scientists have found the first alien atmosphere that isn’t Earth’s. It seems that many of the Earth-like planets scientists have discovered are inclined to orbit red dwarf stars like Earth and that of GJ1132b. I wonder if we specifically target finding red dwarves, will wel increase our chances of finding more and more Earth-like exoplanets that could be capable of having life? It’s something to think about as we continue moving into the future.

Absolutely love this shot from the extremely talented Nicholas Buer. Reminds me of this awe inspiring quote from physicist Brian Greene about the challenge humanity faces to understand the cosmos:
“We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable odds. We all, in one form or another, are trying to make sense of the world around us. And all of these elements lie at the core of modern physics. The story is among the grandest – the unfolding of the entire universe; the mystery is among the toughest – finding out how the cosmos came to be; the odds are among the most daunting – bipeds, newly arrived by cosmic time scales trying to reveal the secrets of the ages; and the quest is among the deepest – the search for fundamental laws to explain all we see and beyond, from the tiniest particles to the most distant galaxies.” — Brian Greene
Today, March 30, 2017, marks a significant and critical step in making affordable space travel more possible than ever.
Last April, the whole scientific community worldwide was watching as Elon Musk’s SpaceX successfully launched and landed the Falcon 9 rocket booster, proving for the first time in space flight history that it was possible to save and collect rockets after being launched into space. This March, SpaceX aims to up its standards by relaunching and re-landing the same rocket booster, which will deliver a communications satellite into orbit for a Luxembourg-based telecommunications company.
Why is this important? Simply put, rocket boosters are the most expensive part to build for any type of rocket. While SpaceX claims to have the most affordable rocket launches in the world, solidifying the concept of 100% reusable rocket boosters can save space programs $18 million per launch and open more doors for cost-effective commercial space travel.
If 100% reusable rocket boosters become a reality, the cost of launching rockets, experiments, and people into space can be significantly lowered to the point where non-scientific commercial space travel can be a common occurrence.
I can only wonder, then, how much and how far this development will impact not only the space industry, but the whole world itself. If this pushes through, there can be few excuses, then, for not recognizing the potential in looking beyond our own orbit and planet. With incredible scientific progress and discoveries happening almost every day, I think it’s only a matter of time before everyone sets their sights on the stars and starts pushing for interstellar travel.
We are no longer limited to our own solar system, and the possibilities that come with recognizing and answering to that are as unfathomable as space itself.
Ever my first post, I’ve had some great comments and questions from people who’ve stopped by my blog, and I’m going to respond to them all in this post to keep things organized!

Q1: In reference to the Emirates’ plans to build a Mars city by the end of the century - do you think they can do it? (question by krrizal)
A: I definitely think anything is possible. With the current rate of technological advancements and rise of interest in space exploration globally, I think there is a lot of support for those who want to go space - and more specifically Mars. Really, there has never been a better time for space to take the forefront of global topics. If Emirates stays on track with their plans, I believe they can build a city on Mars.
