Catchconstellations-blog - A Story Of Starlight

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

Beautiful! Would like to visit all of these places someday <3

The Sun replaced with other Stars

This visualization shows how the sunset could look like to a human observer if our Sun was replaced by some of the other stars in our galaxy with different sizes and magnitudes, namely Barnard’s Star, Gliese 581, Tau Ceti, Kepler-23, Alpha Centauri A, Procyon, Sirius, Pollux, Arcturus and Aldebaran.

It is just a concept, as liquid water and the Earth as we know it could not exist in the vicinity of the most stars in this graphic. Visualizations are based on the absolute brightness, spectral class and the radius of each star.

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!

Milky Way Shows 84 Million Stars in 9 Billion Pixels

Side Note: The two images shown above are mere crop outs from ESA’s recent hit: The 9 Billion Pixel Image of 84 Million Stars. These two focus on the bright center of the image for the purpose of highlighting what a peak at 84,000,000 stars looks like.

Astronomers at the European Southern Observatory’s Paranal Observatory in Chile have released a breathtaking new photograph showing the central area of our Milky Way galaxy. The photograph shows a whopping 84 million stars in an image measuring 108500×81500, which contains nearly 9 billion pixels.

It’s actually a composite of thousands of individual photographs shot with the observatory’s VISTA survey telescope, the same camera that captured the amazing 55-hour exposure. Three different infrared filters were used to capture the different details present in the final image.

The VISTA’s camera is sensitive to infrared light, which allows its vision to pierce through much of the space dust that blocks the view of ordinary optical telescope/camera systems.

Hope for Life on Trappist-1 is a Little Too Bright for Comfort

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. 

Historic Milestone in Space Flight Technology

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.

A Personal Update

Hello everyone! This is just a quick behind-the-blog update from me.

I’ve been applying to NASA internships for the past three months, and I’m sad to say that I was not chosen for any of them. 

I must admit it broke my heart a little bit to see the positions I applied for fill up with no offer extended to me. I really thought I had a good shot at a few of them this time around. I really thought I had a chance.

I’m writing this because I want everyone to know that is natural to feel frustrated and disappointed, and that whatever setback you may encounter is not the end of the world. Just as there are countless stars in the night sky, there are just as many opportunities still waiting for you to find them.

Yes, my heart is heavy from this, but I know I’ll bounce right back. Rejection is a part of life, after all, and no one ever made it to the stars after giving up because of a few rejections.

I’m going to keep moving forward, with my eyes on the stars, doing what I love to do, and I know I’ll get where I want to be someday.

Until then, ad astra!
