SN 1006 supernova remnant

A new star, likely the brightest supernova in recorded human history, lit up planet Earth’s sky in the year 1006 AD. The expanding debris cloud from the stellar explosion, found in the southerly constellation of Lupus, still puts on a cosmic light show across the electromagnetic spectrum. In fact, this composite view includes X-ray data in blue from the Chandra Observatory, optical data in yellowish hues, and radio image data in red. Now known as the SN 1006 supernova remnant, the debris cloud appears to be about 60 light-years across and is understood to represent the remains of a white dwarf star. Part of a binary star system, the compact white dwarf gradually captured material from its companion star. The buildup in mass finally triggered a thermonuclear explosion that destroyed the dwarf star. Because the distance to the supernova remnant is about 7,000 light-years, that explosion actually happened 7,000 years before the light reached Earth in 1006. Shockwaves in the remnant accelerate particles to extreme energies and are thought to be a source of the mysterious cosmic rays.

As stated by Huffington Post

Researchers are now determined that plants have the ability to respond to being chewed. 

Basically, plants in the study were able to “hear” themselves being eaten, creating a type of defense mode against their prey, the caterpillar.

Using a laser microphone, the scientist were able to record the vibrations and sounds of caterpillars chewing on plant leaves. The scientists played them to the plants before caterpillars had a chance to nibble. As it turns out, when plants were exposed to these chewing vibrations for a few hours, they reacted by producing increased amounts of mustard oils — which caterpillars hate!

So technically they can hear (hear as in sense) themselves being eaten alive!

Many articles are springing up with “bad news for vegan community” based on this finding, but researchers only said that this finding will help find new ways to defend plants against pesky insects.

From here, researchers plan to find out how exactly these vibrations are able to be sensed by the plants as they’re being munched on. 

SOURCE & WHERE YOU CAN HEAR WHAT IT SOUNDS LIKE

This is both terrifying and yet, immensely intriguing.

At the heart of most, if not all, giant galaxies lies a supermassive black hole. When dust and gas falls into the central black hole, it heats up and emits intense radiation. Quasars, some of the brightest objects in the cosmos, are powered by these phenomena. In these artist’s impressions of a quasar, the rotating ring of matter, and powerful jets of particles thrown out at close to the speed of light can be seen.

Colorful Hubble Telescope Image Is Best-Ever View of Universe’s Evolution

The Hubble Space Telescope has captured an amazing and colorful deep view of the universe, showing galaxies shining in ultraviolet light during their wild, star-forming “teenage” years.
The new image, which was released today (June 3), is themost comprehensive view of the evolving universe ever captured by the space telescope, Hubble representatives said. Hubble previously imaged the same patch of sky shown in the new image between 2004 and 2009 to create a super-detailed view known as the Hubble Ultra Deep Field.

Stunning photos of tears under a microscope vary by emotion

Follow policymic

"The project, called "The Topography of Tears," captures unique moments in human experience, but there’s also a scientific reason why every tear looks so different. There are three different types of tears: basal (lubricating), reflex (responding to stimuli) and psychic (triggered by emotion). Each type of tear contains different organic substances, and the molecular makeup depends on the causative agent. For instance, emotional tears contain the neurotransmitter leucine enkephalin, a natural painkiller that the body releases to mitigate stress."

there are three ways that individuals who are oppressed can deal with their oppression. one of them is to rise up against their oppressors with physical violence and corroding hatred. but oh this isn’t the way. violence creates many more social problems than it solves. another way is to acquiesce and to give in, to resign yourself to the oppression. but that too isn’t the way, because non-cooperation with evil is as much a moral obligation as is cooperation with good.

but there is another way. and that is to organize mass non violent resistance based on the principle of love. where there is something about hate that tears down and is destructive, there is something about love that builds up and is creative. love is the only creative, redemptive, transforming power in the universe.

when you rise to the level of love, of its great beauty and power, you seek only to defeat evil systems. individuals who happen to be caught up in that system, you love, but you seek to defeat the system. you just keep loving people, even though they’re mistreating you. just keep being friendly to that person. i’m foolish enough to believe that through the power of this love, somewhere men of the most recalcitrant bent will be transformed.
