thirty meter telescope
2013-04-15 04:57:32

redOrbit Staff & Wire Reports - Your Universe Online A plan to build the world´s largest telescope moved one step closer to becoming a reality on Friday, as the Hawaii Board of Land and Natural Resources (BLNR) approved a plan to build the record-breaking instrument at the summit of Mauna Kea volcano. According to Audrey McAvoy of the Associated Press (AP), the ruling allows the US and Canadian universities behind the Thirty Meter Telescope (TMT) project to begin negotiating a...

Unmanned Aircraft Used To Help Study Volcanic Plumes
2013-04-02 05:11:35

April Flowers for redOrbit.com - Your Universe Online Last month, Earth science researchers from NASA traveled to Turrialba Volcano near San Jose, Costa Rica. The research team was there to study the chemical environment of the volcano by flying a Dragon Eye unmanned aerial vehicle (UAV) into the sulfur dioxide plume and over its summit crater. The UAV — a small electric aircraft equipped with cameras and sensors — will help the scientists improve the remote-sensing...

Geologists Say Earth Is Congested
2013-04-01 10:38:38

Brett Smith for redOrbit.com - Your Universe Online According to a new study from a team of German researchers, geological forces are stagnating in certain regions because of pressure-induced phase transitions. The Earth´s crust is in a constant state of flux, with solid slabs diving hundreds of miles down into the mantle as hot liquid magma rises up to fill the gaps. According to study author“¯Falko Langenhorst from the Friedrich Schiller University Jena, these forces...

Iceland's Hekla Volcano Shows Signs Of Activity, No Eruption Imminent
2013-03-27 11:18:32

Lawrence LeBlond for redOrbit.com - Your Universe Online One of Iceland´s most active volcanoes, Hekla, has been showing signs of potential activity as of late, prompting National Commissioner of the Icelandic Police to declare an “uncertainty phase” for the snow-capped peak. Geologists at the Icelandic Met Office reported unusual seismic activity on the mountain over the past two to three weeks, but said there was no sign that an eruption was imminent. The...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Inner Earth Could Have Caused Ancient Climate Change
2013-03-18 19:47:05

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in a newspaper published by the American Geophysical Union that Earth's interior cycles have contributed to long-term sea-level rises and climate change. New York University and Ottawa's Carleton University scientists say activity below the earth's surface has played a role before in ancient rises in sea levels and global warming. Although it may seem like welcoming news for climate change skeptics, the authors...

Mercury May Have Hosted A Magma Ocean In Its Past
2013-02-21 13:29:25

Lee Rannals for redOrbit.com - Your Universe Online Scientists analyzing data from NASA's MESSENGER spacecraft say that Mercury once harbored an ancient magma ocean. An MIT team of scientists say that Mercury may have had a large ocean of magma very early in its history, shortly after its formation about 4.5 billion years ago. A group of scientists analyzed X-ray fluorescence data from MESSENGER collected back in 2011. They were able to identify two distinct compositions of rocks on...

New Owl Species Discovered In Indonesia By Its Unique Whistle
2013-02-14 07:35:57

Lawrence LeBlond for redOrbit.com - Your Universe Online A new species of owl has been discovered in Lombok, Indonesia by two researchers just a few days apart from one another in early September 2003. But it was not the plumage that gave this bird away. The unique night song of the Rinjani Scops owl (Otus jolandae) caught the attention of these two scientists, offering evidence that the island of Lombok has its first recorded endemic bird species. Nearly a decade later, the first...

Volcano Controversy Settled Using Chemistry ‘Trick’
2013-02-12 15:01:41

Brett Smith for redOrbit.com - Your Universe Online Volcanic eruptions have been known to cause global cooling, although the extent of this cooling has been a topic of scientific controversy. Now a team of atmosphere chemists from the Tokyo Institute of Technology and the University of Copenhagen has devised a method for determining which historical cooling periods are the results of volcanic eruptions. When a large volcano erupts, it can propel gases high into the stratosphere where...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Jabal al-Tair Island
2014-04-10 11:56:15

Jabal al-Tair Island, known by many other names including Tair Island and Jebel Teir, is a volcanic island that is located in the Red Sea and is under the jurisdiction of Yemen. It reaches an elevation of 801 feet and is about 1.9 miles in length. The island is comprised of Jabal al-Tair, a stratovolcano that was considered extinct in 1982, although it erupted in 2007. In 1900, the British Admiralty described the volcano as having a steep, conical shape, making it a good landmark for ships...

Mauna Kea
2014-04-10 11:49:35

Mauna Kea is a dormant shield volcano that is located on the island of Hawaii and reaches an elevation of 13,803 feet. It is one of five volcanoes that comprise the island and is thought to be about one million years old. Mauna Kea, like all Hawaiian volcanoes, was created when the Pacific tectonic plate passed over a volcanic hotspot. The Hawaiian volcanoes, which extend over an area known as the Hawaiian Ridge – Emperor Seamount chain, have been well studied, but it is not known how the...

Zubair Group
2014-04-10 10:08:46

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....
