Venus, a planet without intrinsic magnetic field hosts magnetic storm

Venus, a planet without intrinsic magnetic field hosts magnetic storm | Solar System - SSMS | Scoop.it

When magnetic fields of opposite polarity collide and merge, they unleash a torrent of energy. The process, known as magnetic reconnection, can cause flares on the Sun and magnetic storms and shimmering auroras on magnetized planets with substantial atmospheres, such as Earth, Jupiter and Saturn. Now scientists have discovered that magnetic reconnection also happens on Venus, a planet with no intrinsic magnetic field. The finding, reported today in Science1, suggests that magnetic reconnection may generate auroras on Venus, and could have contributed to the loss of a thick, water-rich atmosphere that scientists believe surrounded the planet during its early history, some 4 billion years ago.

[VIDEO] - Venus Cloud Tops Brace For Sun's 'Floral' Flare

[VIDEO] - Venus Cloud Tops Brace For Sun's 'Floral' Flare | Solar System - SSMS | Scoop.it
The Sun produced a colorful flare on January 16, 2011 resembling a flower and the ensuing coronal mass ejection was pointed towards Venus. Damage to the planet's vast atmosphere is expected to be minimal, with slight cloud top erosion.

Via Sakis Koukouvis
SSMS Science's insight:

Coronal mass ejections can be very powerful. If one strong enough hit earth, it could wipe out radio communication, power lines, and various other very bad things. The reason the CME would cause aurora borealis, also known as northern lights, is because when the sun has a solar storm, it sometimes shoots radiation out into our solar system. If this ejection hits a planet, the gravitational pull would take these particles and pull them towards the poles of the planet. The radiation would then make what we know as the northern lights. I used to think that the aurora borealis only could happen on earth but, I guess it can also happen anywhere in the universe. ET

Comet ISON begins to brighten on its trip towards the sun

Comet ISON begins to brighten on its trip towards the sun | Solar System - SSMS | Scoop.it
Comet ISON has the potential be one of the brightest comets to fly past the Earth in many years. However, so far the brightness of the comet has been rather disappointing to astronomers and amateur skywatchers.

Via Thomas Faltin
SSMS Science's insight:

One of the brightest comets to probably fly past Earth in many years is comet ISON. The brightness of this comet has disappointed amateur skywatchers and astronomers. Comet ISON has not been as bright as people were hoping it would be. But, recently, ISON has become much brighter and it's tail has gotten a lot longer. Since it's becoming brighter and it has a longer tail, astronomers are hoping it has gotten back on track for a bright show when it comes closest to the sun later this month. Right now, the comet remains intact. Astronomers all around the world said that the comet has a magnitude of 9.0 right now. However, we can't see it because it is too dim. The dimmest light we can see has a magnitude of 6.5. ISON will have to brighten up, so we can see it. I am excited to hear about comet ISON later this month! CB

Solar Flares Pack the Power of Millions of H-Bombs

Solar Flares Pack the Power of Millions of H-Bombs | Solar System - SSMS | Scoop.it

Exploding from the Sun’s surface with energy equivalent to millions of 100-megaton hydrogen bombs, the flare spewed intense radiation into space. It was not directed toward Earth, but NASA says solar material from all three of the recent flares will pass by the Spitzer Space Telescope  and could give a “glancing blow” to the STEREO-B and Epoxi spacecraft. All these spacecraft can be put into a protective safe mode.

 

The latest eruption was characterized as an X3.2-class flare. The X-class category is the most powerful, and each step up in number indicates a doubling of energy. So this flare was more than twice as powerful as Sunday’s X1.7-class flare.

 

The panel of images above, from NASA’s Earth-orbiting Solar Dynamics Observatory spacecraft, shows the massive eruption of energy in four different wavelengths. Each panel shows what was happening at a different temperature. According to NASA, this provides scientists with insights into the causes of solar flares.


Via Dr. Stefan Gruenwald
SSMS Science's insight:

Solar flares are very powerful. In fact, sometimes, when one erupts it will shoot out and then come back down making an arc of plasma called a prominence. Normally, these arcs are so big that you could run the planet Jupiter through one without touching any of the sides. When a giant solar flare happens, sometimes a big ball of radiation particles shoot out. Now, if this ball were to hit earth, if big enough it could knock out power, communication lines, radio waves, and in general cause mayhem. What's even more cool is that compared to some other stars in the universe, the sun can be considered small. This is just one example of how amazing the universe is. ET

Major volcanic eruption seen on Jupiter's moon Io

Major volcanic eruption seen on Jupiter's moon Io | Solar System - SSMS | Scoop.it

One of the most massive volcanic eruptions in the solar system has been spotted on Jupiter's moon Io – by a telescope perched on a volcano on Earth.

 

On 15 August the Keck II telescope on Mauna Kea in Hawaii recorded fountains of lava gushing from fissures in the Rarog Patera region of Io. Heated by gravitational squeezing from Jupiter and its other moons, Io is covered in volcanoes that erupt almost continuously. This event is easily in the top 10 yet seen on Io by humans, says Ashley Davies of NASA's Jet Propulsion Laboratory in Pasadena, California.

 


Via Dr. Stefan Gruenwald
SSMS Science's insight:

Recent observations on lo, one of Jupiter's moons, has shown a huge volcanic eruption there. It is 390,400,000 miles from Earth. lo is the innermost of the four largest moons around Jupiter, and is the most volcanically active object in the Solar System. Dr. Imke de Pater said that this eruption is one of the top ten most powerful eruptions that have been seen on lo. She said, "It is a very energetic eruption that covers over a thirty square kilometer area." She said that is appears to have a large energy output. lo's eruptions can't be seen from Earth, but infared cameras have been able to show that there are likely fountains of lava flowing from it. There has been no photos or data on the eruption, since scientists are still making observations on it. They think a gravitational pull between Jupiter and lo is one cause of the moon's intense vulcanism. I think it is fascinating to see volcanic eruptions somewhere else than Earth. CB

During the rover’s descent to the planet, the Mars Descent Imager (MARDI) was busy capturing images at 4 fps. While these images have been used to pinpoint the landing location on the planet’s surface, they also provide a great video of the descent from the rover’s perspective.

Just a little bit over two weeks ago, NASA's Mars rover, Curiosity, landed on Mars. It took some cool pictures as it was landing. The pictures provide an amazing video of the descent of Curiosity. The pictures were taken by the Curiosity itself. When the rover landed, it took some pictures of Mars. The first image it took is tilted on an angle because Curiosity's arm was not extended yet. The rover took a few more pictures before it left its landing point. New and amazing videos and pictures are put up each day. Soon, it will be on its way to the base of Mount Sharp, and will stop and explore things on the way. It is amazing to see pictures that were taken on other planets, and to learn more about what they look like. CB

Massive solar flare 'could paralyse Earth in 2013'

Massive solar flare 'could paralyse Earth in 2013' | Solar System - SSMS | Scoop.it
The sun is leaving a notably quiet period and scientists expect to see an increase in solar activity, accompanied by unprecedented levels of magnetic energy.

 

A massive solar flare could cause global chaos in 2013, causing blackouts and wrecking satellite communications, a conference heard yesterday.

Nasa has warned that a peak in the sun's magnetic energy cycle and the number of sun spots or flares around 2013 could generate huge radiation levels.

The resulting solar storm could cause a geomagnetic storm on Earth, knocking out electricity grids around the world for hours, days, or even months, bringing much of normal life grinding to a halt.

Defence Secretary Liam Fox, who delivered the keynote address at an international conference on the vulnerability of electricity grids around the world, warned that modern societies' dependence on technology leaves them vulnerable to such events

The sun erupted with two of the strongest solar flares it can unleash Friday, just days after blasting an intense solar storm at Earth.

SSMS Science's insight:

Solar flares are very interesting. When large ones erupt, mass amounts of radioactive material can shoot towards Earth. Reaching our planet may only take a bit less than a day. One time, in 1869, such a strong solar flare erupted the material shot toward Earth and knocked out telegraph lines and caused auroras to be seen all the way in Southern Europe. Today, if a solar flare that large erupted, power would most likely stop. Almost all communication would probably cease because of various factors. This just shows how powerful our sun, however plain it might be to the naked eye, is. ET

A tale of two planets | ClimateNewsNetwork.net

A tale of two planets | ClimateNewsNetwork.net | Solar System - SSMS | Scoop.it

There is already a runaway greenhouse effect on the planet Venus: all the oceans have boiled away, the clouds rain sulphuric acid and the atmosphere at ground level is hot enough to melt lead. The only comfort is that if such a transformation does affect the Earth, it probably won’t be for a billion years or so.

 

Colin Goldblatt of the University of Victoria in Canada and US colleagues report in Nature Geoscience that they have been taking a new cool look at what makes one terrestrial planet temperate and stable and the other so hot that the ocean boils away, and the answer is disconcerting. Both outcomes are possible for a planet that receives the same level of solar radiation as the Earth does today. “A runaway greenhouse could in theory be triggered by increased greenhouse forcing, but anthropogenic emissions are probably insufficient,” the authors say, comfortingly.

 

The research grows out of a continuing academic interest in the unusual condition of planet Earth – just far enough from the Sun for water to freeze but near enough for some of it to melt and evaporate, massive enough to retain an atmosphere and clouds of water vapour but small enough for a gravitational pull that will allow complex creatures to evolve, grow tall and even fly. Goldilocks, the girl in the British fairy story, chose the porridge that was not too hot, not too cold, but just right, and planetary scientists have co-opted the imagery, and dubbed the Earth the Goldlilocks planet.

I know there have been ideas about settling on other planets in our solar system but, I don't think Venus is one of them. Although it is the same size as Earth, the similarities basically stop there. Just the fact that it rains sulphuric acid makes it uninhabitable. There is also the atmosphere, temperature, and availability of water and food that deems it not fit for living. I have sometimes wondered why God would put something of no use in space. I think though that the answer might be to show His amazing power. He made billions of stars, galaxies, planets, and other space wonders to show us how significant He is and how insinificant we are and I think, by just looking at one of many planets, Venus can show us how great ore God is.
