Super Earths and Exoplanets

 

we explore further afield from our home planet, we learn there are not only other systems, but many other planets in these systems. There are people who look to these for another earth and for alien life.

Planets outside of our solar system are called exoplanets.

Just as our solar system has planets of different sizes and types, planets in other systems are varied in size and composition.

To date, we have found 3,242 systems with planets, many with multiple planets, bringing the number of exoplanets we know of to 4,395.

Planets are categorized by their mass. Any planet with a mass larger than earth without being 14 times higher in mass is considered a super-earth. 

The designation doesn't speak to its composition or whether it would be a friendly place for us humans to live. It only tells us the comparative mass of an exoplanet.

Recently, NASA discovered a new super-planet naming it TOI-561b.

TOI-561b travels around its sun twice as fast as we travel around ours. So it experiences two days in the time we experience one.

Life is unlikely to exist there as the temperature on it is 3,140 degrees Fahrenheit.

Yet, it is exciting to keep discovering more and more systems and planets. Perhaps, one day, we'll find one more compatible with life on our earth,

NASA and the Space Age

In 1957, an amazing spectacle appeared in the North American night sky – Sputnik, the first satellite to enter Earth’s orbit. The USSR had successfully sent a rocket into outer space, thus beginning the space race, an event which would last a decade and challenge the best and brightest of two nations.

In response to Sputnik, President Dwight D. Eisenhower created NASA, the first American administration for space exploration in 1958. With Project Mercury, NASA attempted to make the first manned mission into space but failed to beat the Russians, who sent Yuri Gagarin into orbit in 1961. A month later Alan Shepard became the first American in space and John Glenn followed soon after, orbiting the Earth three times in 1962.

In the Sixties, NASA entered a new era. With the cold war raging and the threat of nuclear armament on the horizon, President John F Kennedy vowed to redouble NASA’s efforts and put an American on the moon by the end of the decade. In 1965, NASA began the Spacelab project, sending the first space station into Earth’s orbit. Despite sustaining damage during take off, the station was repaired in space and orbited the Earth until 1979.

The success of Spacelab led to NASA’s famous Apollo missions to the moon. After many failed attempts, Apollo 8 became the first shuttle to circle the moon in 1968. The following year, the USSR accomplished its first moon tour, leaving the space race at a stalemate.

With the cold war raging in the east, astronauts Buzz Aldrin and Neil Armstrong of Apollo 11 successfully landed on the moon in 1969. The mission effectively ended the space race and cemented America’s place as the world leader in space exploration. Buzz Aldrin and Neil Armstrong became national heroes and were awarded the Presidential Metal of Freedom later that year.

Since then, NASA has continued its exploration of space sending probes to every planet in our solar system, including the dwarf planet, Pluto. It also landed four rovers on Mars, the last of which, Curiosity, is still collecting data from its craters today.

The recent image of a black hole in the M87 galaxy is more proof of human potential in space exploration. For the Space Age to advance, we must continue NASA’s legacy into the future.

How the Stars Got Their Colors

After seeing hundreds of dazzling galaxies and nebulae in print, one might have a preconceived notion of what it’s like to look through a telescope. The reality, however, is somewhat different.

Celestial objects such as galaxies, star clusters, and planetary systems are some of the most beautiful treasures in outer space. Unfortunately, they’re so far away that they mostly appear faint to the naked eye, even when viewed through a telescope. The problem is that, unlike a camera, our eyes cannot adjust their exposure time in order to soak up more light from these distant objects.

For astrophotographers to get the vibrant colors of a nebula or galaxy, they need to rely on a number of techniques, including long exposures, color compositing and sometimes editing in post-production.

Eagle Nebula, Messier 16. SS2596669.

The famous Eagle Nebula pictured here is actually three monochromatic images mapped to different color wavelengths combined to create one image. Some might say that this makes it fake or embellished but the truth is more complicated.

The colors that astrophotographers use to create images like this reflect the chemicals in the celestial objects themselves, so they are drawn from real scientific data. Nevertheless, it’s still unclear how accurate the colors actually are.

Of course, visual perception is always subjective, limited by our eyes and brain, so it’s worth considering how accurate our image of reality ever is.

Science in Motion – The History of Discovery in Video Montage

Have you ever wanted to step into an old etching and explore the laboratories of your favorite scientists and inventors? Short of magic, video montages provide the next best thing!

Peer into Herschel’s telescope as he gazes at the cosmos from his observatory or follow a beam of light as it refracts into a rainbow in Newton’s laboratory.

Video Montage Gallery

Beyond the fun, video montages have an educational value. By linking images together, montages provide historic continuity, allowing people to see the connections between scientific discoveries. An etching from Isaac Newton’s life may tell you something about his findings in optics, but a group of images reveals how they led to further insights into physics.

Montages also bring clarity to scientific discoveries. By zeroing in on a lab experiment, montages highlight key components involved in the scientific process. Panning and scrolling help viewers understand the causes and effects involved in experiments, giving them a better understanding of how science works.

As classic images enter the digital sphere, video montages are providing a unique and fun visual aid for designers and educators alike. Take a closer look below!
