Alien Solar System Is a Lot Like Ours, Say Astronomers
Using NASA's Kepler space telescope, astronomers have found an alien solar system that exhibits the same structure as ours, with planets rotating on a single plane around their parent star.
What's the Latest Development?
Examining data from NASA's Kepler space telescope, astronomers have found that an alien planetary system bears many similarities to our own, confirming parts of planet formation theory which suggest that most planetary systems begin in similar fashion. "Researchers studying the star system Kepler-30, which is 10,000 light-years from Earth, found that its three known worlds all orbit in the same plane, lined up with the rotation of the star—just like the planets in our own solar system do." The planetary system consists of three known extrasolar planets circling a sunlike star, all of which are much larger than Earth.
What's the Big Idea?
Since its launch in March 2009, the Kepler space telescope has located more than 2,300 potential alien worlds, 700 of which have been confirmed as genuine planets. "Kepler uses the 'transit method,' noting the telltale brightness dips caused when a planet crosses, or transits, a star's face from the telescope's perspective. In the new study, the scientists studied Kepler observations of the extrasolar system even more closely." While we once believed our position in the cosmos was privileged, it is becoming clearer than our solar system, sun and planet may be rather ordinary. Astronomers have identified between five and ten alien planetary systems where they can further test their theories.

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
We explore the history of blood types and how they are classified to find out what makes the Rh-null type important to science and dangerous for those who live with it.
- Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
- Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
- It's also very dangerous to live with this blood type, as so few people have it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
