Europa – Our Potential Habitable Environment

What is the first criterion to defining a habitable environment for humans? Water to sustain life. Through NASA’s Hubble Space Telescope, scientists were able to observe water vapor above the south polar region of Europa, providing the first solid evidence of the existence of an ocean under Europa’s icy crust.

Researchers are able to speculate that the water vapor is most likely generated when water plumes erupted on the surface. If these findings are proven to be true, this would make Europa the second moon in the solar system known to have water vapor plumes. Also, the evidence provides a general idea of the chemical makeup of Europa and its potential of becoming a habitable environment, without digging through the layers of ice.

Since this moon has a strong gravitational pull, majority of the -40°F vapor would fall back onto the surface, rather than escaping into space. This new observation, if confirmed, can demonstrate the reliability and power of the Hubble Space Telescope, and its ability to explore new worlds for potentially habitable environments in our solar system.

New Discovery: Young Planet Found Outside of Solar System

Have your Blaster been keeping up with the latest space happenings? It seems that a team of astronomers have discovered a giant planet, orbiting a single, sun-like star, right outside of our solar system. What’s most unique about this planet? It weighs 11 times more than Jupiter’s mass, and it is orbiting its star at 650 times the average Earth-Sun distance, which is a formation model that cannot be explained by present theories and knowledge.

This young planet is about 13 million years old, and it still glows from the heat that was created during its formation. Earth was created 4.5 billion years ago, which is 350 times older than this giant planet, known as HD 106906 b. Its temperature is about 2,700°F, which is much cooler than its host stars, and thus, emits most of its energy as infrared, not visible light.

Since this planet is orbiting very far from its parent star, astronomers are very puzzled and confused about its odd formation. None of the present theories sustained. This new discovery provided astronomers the opportunity to question planets’ formation, history, and composition.

Medium-sized Black Holes

Did you and your Blaster know that black holes come in two extremes – the petite ones with a mass that is only 10 times that of our sun, and monstrous ones that have a mass equivalent to 10 billion suns? However, NASA recently found some interesting data that shows that we may found a new medium-sized category of black holes.

Although scientists is yet to determine what caused the formation of intermediate-sized black holes, with theories surrounding the notion of clustering and merging of stars, evidence shows that the proposed medium-sized black holes came from objects called ultraluminous X-ray sources (ULXs), where the black hole feeds off a normal star. The feeding process is similar to that of supermassive black holes, but less messy. While supermassive black holes are located at the cores of galaxies, ULXs are scattered throughout the galaxies.

Astronomers found that a ULX located 13 million light-years away has a mass that is about 100 times of our sun, which puts it right at the border between small and medium black holes. However, some scientists made the conclusion that the evidence showing the ultraluminous quality of these objects are caused by the high rate of material absorption, not from the size. Therefore, the existence of medium-sized black holes has yet to be determined.

Latest Space Finding: Jets in our Supermassive Black Hole

Do not mistake these jets as a type of plane that we can see flying through Earth’s skies. In this case, the term “jet” refers to high-energy particles that can be found in space. Categorized under a branch of scientific study, called particle physics, these jets are believed to be produced when materials that were originally falling towards a black hole are redirected outwards. In fact, this amazing occurrence plays an important role in transporting energy and regulating the rate of new star formations.

Why is finding a jet so important to scientists? It helps them determine the direction of the black hole’s spin axis, which allows them to make more accurate assumptions about the growth and history of the black hole. Since the study found that the black hole is pointing to the same direction as the Milky Way, astronomers are able to insinuate that gas and dust have migrated steadily into the black over instead of colliding with large galaxies.

Since the activity of the giant black hole has been relatively low over the past few hundred years, the jets surrounding appears to be weak. However, scientists speculate that the jet may brighten dramatically when the black hole starts consuming material more actively.

Solar System Crafts for Kids

Are you looking for some exciting and educational science projects to enjoy with your young Blaster? Teach them a little more about our very own galaxy by creating a beautiful solar system project for your home. As your kids might already know, our solar system consists of the Sun and eight surrounding planets, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, neighbored by the dwarf planet, Pluto. You can share the wonders of our universe and the science behind the orbiting circuit with your family by building one of our favorite crafts that gravitates toward children’s natural curiosity.

Physical Models
Building a physical model of the solar system with your kid can improve their visual development and hand-eye coordination. Please note that the relative sizes of the planets and the Sun is as follow (starting from the largest to smallest): Sun, Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, and lastly, Pluto. To create a more accurate depiction of the solar system, try using the following materials and methods:

Space News Brings Historic Memories

The moon has been the subject of many different scientific experiments throughout the years. Now, Russia is making plans to do further research on the moon by sending an unmanned spacecraft in 2015. The Russian Space Agency said that they would be launching a space exploration vehicle that weighs about 1,100 pounds. To add on to this load, the spacecraft will be carrying over 50 pounds of equipment so that scientific experiments can be held. This spacecraft’s main goal will be to take soil samples and search for sources of water on the moon. Moreover, this expedition to the moon is significant to the Russian Space Agency because its last unmanned flight to the moon was in 1976.

These events bring a particular period in history to light — the Space Race. In short, the Space Race was a competition for space exploration supremacy between the Soviet Union and the United States. This “competition” developed during the Cold War between the years 1957 and 1975. The Space Race’s main focuses were in developing and launching artificial satellites, conducting human spaceflight around our earth, and sending spacecrafts on trips to the moon.

All of the technologies that were being developed at this time were centered around a couple of key goals: to attain technological superiority and reaffirm national security. The Space Race began at a neck-and-neck pace; the United States and the Soviet Union started off the Space Race with public announcements about launching satellites into space. These announcements were made within a couple of days of each other in 1955, which makes it clear that a type of “competition” or “race” had begun.

One of the key concerns that were sparked by the Space Race was international peace and national security. For instance, with satellites and spacecrafts flying overhead, President Eisenhower was concerned that the Soviet Union would claim that their national airspace was being breached. These concerns, among others, were just an example of the type of competition that was developing through the Space Race.

The Space Race effectively concluded in 1975, when the United States and Soviet Union cooperated in a human spaceflight mission entitled the Apollo-Soyuz Test Project. Although the Space Race seems to have been purely about the nations besting each other in technological and scientific exploits, this is not the case. In fact, the Space Race led to different advances in education, research, and environmental movements.

Though the Space Race is a thing of the past, we can look to the events which took place during this time and applaud those who pioneered many of the technologies that our nations use today. Do these types of historic and scientific facts get your Blasters’ brains buzzing with what they could do in the science world when they grow up?
