Scientists produce some amazing images while performing their research. Astronomers are no different. An April 11, 2013 solar flair provided astronomers the opportunity to track the sun’s solar cycle.
Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours.
The flare’s coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space, reached Earth one day later producing a temporary radio blackout.
It also produced the incredible image that is today’s cool image. Available as a 16″ X 20″ poster at our store.

Explanation: The Elk Bath picture was taken by the Alaskan Type I Incident Management Team on August 6, 2000 on the East Fork of the Bitterroot River on the Sula Complex. The year 2000 fire season in the continental United States was one of the most active on record, burning an area similar in size to New Jersey. This photograph was taken with a digital camera.

Explanation: It was a quiet day on the Sun. The above image shows, however, that even during off days the Sun’s surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius. Large sunspot group AR 9169 from the last solar cycle is visible as the bright area near the horizon. The bright glowing gas flowing around the sunspots has a temperature of over one million degrees Celsius. The reason for the high temperatures is unknown but thought to be related to the rapidly changing magnetic field loops that channel solar plasma. Large sunspot group AR 9169 moved across the Sun during 2000 September and decayed in a few weeks.

A view of one of the first full-energy collisions between gold ions at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider, as captured by the Solenoidal Tracker At RHIC (STAR) detector. The tracks indicate the paths taken by thousands of subatomic particles produced in the collisions as they pass through the STAR Time Projection Chamber, a large, 3-D digital camera.

What Is Science?
Investigating the World around Us

The six Ws of journalism and police investigations to elucidate or investigate a saturation — who, what, when, where, why, and how.

|Science is one method of investigating the universe. Many people think of science as chemistry, geology, etc. These are fields or bodies of knowledge discovered through science or areas investigated through science. Science, loosely speaking, is a technique of investigating the observable world around us in a systematic manner and explaining it in a testable, repeatable fashion.
However, science isn’t the only technique available to us.
The Six Ws (also known as the Five Ws or the Five Ws and one H) used by journalists and police are consider fundamental for getting the "full" story on something. The idea is that for a investigation to be considered complete it must answer the six questions represented by an interrogative word — who, what, when, where, why, and how. These interrogative words should be answered by a verifiable factual answer. It is of importance that none of these questions can be answered by a simple "yes" or "no" answer.
Philosophy uses a systematic approach and a reliance on reasoned argument to study general and fundamental problems. Philosophy looks at areas such as existence, knowledge, truth, justice, beauty, validity, mind, and language.
Spirituality seeks to achieve communion, identity with, conscious awareness, or re-integration with the ultimate reality, spiritual truth, or Godhead. Spirituality uses direct experience, intuition, or insight.
I’m sure those of you who believe in God, found your fate in God not by using science but through some combination of religious/spiritual experience.
Trial and error is a general method of problem solving to obtaining knowledge.
One decides on a possible answer and then applies it to the problem. If the solution is not successful, another possibility is selected that is subsequently applied. The process continues until a solution is found or one gives up.
Exploration is a time honored method of gaining knowledge.
Who can forget past explorers such as Marco Polo, Christopher Columbus, Captain James Cook, Sir Edmund Percival Hillary, and Neil Alden Armstrong. Today many of our explorers are not humans but machines we have created to act as our surrogates. In our past exploration of space the Galileo, Viking, and Pioneer missions gathered information for us. Today other missions such as the Mars Exploration Rovers, Spirit and Opportunity, continue our exploration of space.
Human and machines explorers through history.
No one technique is necessarily any better than another. It just depends on what you’re are trying to learn.
