Huge supervolcanoes may have shaken early Mars

It’s been a big past few weeks for Mars news: the discovery of water in the soil, the sad news that there’s less and less evidence for current life, and now a new theory that the planet might be home to some of nature’s most destructive volcanoes.

 We already know Mars has some big volcanoes. Olympus Mons, the tallest mountain in the solar system at three times the height of Mount Everest, is actually volcanic. (Via European Space Agency)

But it’s nothing compared to the supervolcanoes that might have helped shape the planet’s surface.

In a new article for Nature, scientists claim to have found several possible supervolcanoes in the planet’s northern hemisphere, basing their findings on several huge craters that don’t appear to be asteroid strikes.

See, when a normal volcano erupts, it tends to leave behind a tall mountain-like structure. But with supervolcanoes, so much pressure is released that the ground actually collapses. (Via History Channel)

Just to give you some perspective, Earth has its own supervolcanoes, including one under Yellowstone National Park. YouTube’s popular SciShow has some terrifying numbers for you.

“Its eruptions can eject nearly 250 cubic miles of ash, dust and gas. For comparison, that’s about 1,000 times the volume of Mount Saint Helen’s eruption in 1980.”

But while the thought of massive Martian eruptions is pretty cool — I mean, look at this animation — at least one volcano expert thinks we should cool our jets. (Via Nature)

He tells National Geographic: “Every decade or two someone proposes yet another otherwise previously unrecognized volcano on Mars.” He adds that while the new study looks pretty solid, it, “rests on interpretation of the Martian surface, which has a long history of misleading observers.”

But if early Mars history really did include supervolcanoes, the massive explosions might have actually caused Mars to become habitable.

One of the researchers tells the BBC: “These volcanoes spew loads of gas and dust into the atmosphere. For one thing, that gas becomes the atmosphere."

So if there ever was life on the red planet, it might have owed its existence to some of the most destructive forces in nature.

Navy sailor faces desertion charge after having baby

            Navy sailor faces desertion charge after having baby

Ana Lucia Gnecco, a U.S. Navy sailor, has been jailed in Florida for allegedly deserting her post after giving birth to her daughter. She was arrested at her parents’ home Saturday and is on military hold in a Broward County jail.

Gnecco is a seaman quartermaster who welcomed her daughter into the world in August and was due back to her post in Portsmouth, Virginia, on Jan. 14. However, she never showed up to work.

The arrest was the last resort,” Christina Johnson, a Navy public affairs officer for the medical center, said. “You’re going to want to try and work with the sailor to get them back because the consequences for desertion are serious. She was in contact with her command and the Navy’s arm that would bring her back to duty. All efforts were made to get her back to work, but she chose to stay there.”

The Navy considers any failure to return after 30 days to be desertion. Gnecco enlisted in 2014 and is on contract until 2019. Her father Armando Rodriguez is unsure of the reason why she didn’t return to work but assumes it revolves around her baby.

“The baby could be the reason, We could assume that having a baby might not go well with serving in the military,” he said. “I hope that she goes back up there and they have a hearing and she is released. There is no point in keeping her.”

“We are almost at the end of the parade route,” the band posted to its Twitter and Facebook social media accounts. Also, the Northeastern Local School District Superintendent John Kronour confirmed tonight that he had not heard of any local injuries.

Video attached shows the band making preparations on Thursday for this parade. There are 108 students in the band participating. They raised money for the trip by selling cookie dough, pizza and raffle tickets.
