Look 4 Billion Years Into The Past With This Epic Image From Hubble

You’ve never seen a constellation like this before

Your galaxies are lovely, Hubble.

As part of its ongoing mission to explore new frontiers in the vast continuum of space, the Hubble Space Telescope continues on its three-year Frontier Fields program. Its latest target is the distant galaxy Abell S1063, which, according to Hubble scientists, is “potentially home to billions of strange new worlds.”

In an image released on Thursday, you can see the cluster in the center as it was four billion years ago, and thanks to gravitational lensing, Hubble is able to explore galaxies even earlier in time. While such galaxies might have been impossible to see otherwise, gravitational lensing enhances light from the galaxies behind it, leading to the discovery of galaxies as they appeared billions of years ago. One of the galaxies hidden behind Abell S1063, for example, is about 12.7 billion years old, according to

Sixteen background galaxies have also been discovered by the distortion of Abell S1063, which will contribute to the study of dark matter and its gravitational pull. As the Hubble team explains, “The huge mass of the cluster distorts and magnifies the light from galaxies that lie behind it.” This distortion of space and time “allows Hubble to see galaxies that would otherwise be too faint to observe and makes it possible to search for, and study, the very first generation of galaxies in the Universe.”

Abell S1063 is the fourth galaxy cluster to be studied as part of the Frontier Fields program, and two more will be explored over the next few years. Even if this sounds like a bunch of Hubble hubbub, at the very least these images reveal a remarkable sliver of the vast expanse we have yet to explore.


When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.

At this point most reasonable people agree that climate change is a serious problem. And while a lot of good people are working on solutions, and we're all chipping in by using fewer plastic bags, it's also helpful to understand where the leading causes of the issue stem from. The list of 20 leading emitters of carbon dioxide by The Guardian newspaper does just that.

Before the release of "The Joker" there was a glut of stories in the media about the film's potential to incite violence.

The FBI issued a warning, saying the film may inspire violence from a group known as the Clowncels, a subgroup of the involuntarily celibate or Incel community.

Incels an online subculture who believe they are unable to attract a sexual partner. The American nonprofit Southern Poverty Law Center describes them as "part of the online male supremacist ecosystem" that is included in its list of hate groups.
