This video zooms into the small areas of sky that the Hubble Space Telescope was aimed at to construct the extreme deep field,or XDF.
The region is located in the southern sky,far away from the glare of the milky way.
The bright plane of our galaxy.
in terms of angular size,the field is a fraction the angular diameter of the full moon,yet it contains thousands of galaxies stretching back across time.

Hey guys, thought you might be interested in another design I made. Any feedback would be much appreciated - I'm trying to use money from these designs to supplement my very limited student income hahah. :)

You can get it on t-shirts, posters, hoodies, mugs, stickers, cards, throw pillows, and way way more. Even if you're not interested in buying, I'd really appreciate any shares, +1s, etc, as it all goes a long way to helping me out :)

Thank you so much :D

I made it using a NASA image of the Horsehead Nebula, editing it into the faces of a Penrose triangle with segments of the image offset to give it the illusion of being space warped into an impossible 3-dimensional shape

The rocket turbopump was designed by the engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama (in collaboration with outside vendors). And, the best part is, now the 3D-printed component has been successfully tested, thus alluding to the potential application of the technology in 3D-printed demonstrator engines for rockets.
NASA tests one of the most complex, 3D-printed rocket turbopump ever made, inside Marshall Space Flight Center in Huntsville, Alabama.

This is a photo taken by the Hubble Space Telescope of the pair of galaxies NGC 4038 and NGC 4039, otherwise known as the "Antennae Galaxies."

Once upon a time, these two galaxies were normal everyday spiral galaxies like the Milky Way, but over the last few hundred million years, they have been spending their time smashing into each other. In fact, their collision is so violent that stars are being torn from their host galaxy, forming a connecting arc between the two resembling antennae.

These galaxies are said to be in a state of "starburst", meaning that all available gasses in these galaxies are being used to form stars at an incredibly fast rate. These clouds of gas can be seen as bright pink or red, and surround the blue star-forming regions.

Eventually the nuclei of these galaxies will combine, and will form one  large elliptical galaxy.

For billions of years we weren't so lucky. Our ancestors, from the first life forms, couldn't do, or comprehend, what only we now can. The universe is terribly hostile to our kind of life. Now we know that we are the star-stuff, the universe, that has finally become conscious of itself.

+Rae Smith no one's saying he's not able to speak (entitled is a strange word... in general there's too much entitlement everywhere, especially with celebrities and teenagers, he' sa celebrity).
And really he has no serious interest in the subject. That's why this podcast is a comedy piece. If you take the subject seriously you don't do a comedy piece on it. It's funny. I'm actually glad I listened to it. But he certainly isn't "entitled" to it. There isn't even 5 seconds worth of actual thoughtful opinion, so the whole issue is irrelevant. That's why I changed my tone from critique to enjoyment.

But seriously, it's like asking a tone deaf man about the difference in sound between compressed music, full wave, wood acoustic speakers or a bose wave system... digital or analogue... it's just straight up outside of their wheelhouse, just like anything involving God is for him. When he's ever been asked in any serious capacity, he doesn't launch into ridiculum like Dawkins does, or specious (if polite) exaggerated version of real claims like Hitchens used to (he will be missed, he was at least thoughtful and civil). But when He HAS been open, it's been more unserious and/or philosophically vague.

It's just not where anyone should get a serious answer on the subject.

Ok...we have a rogue (Wise) planet, 7.2 light years away in the Hydra constellation. How does this knowledge help (in any way) with all the problems on a small class M planet called EARTH?!

I once thought we have no business in outer space but I now think it is ok based on my changing opinion but IT seems human to explore.

Sol: not guilty of stealing minor planets

"one can always burden failing explanations with ad hoc hypothesis"
(Occam's razor, Wikipedia)

In general, secondary ad hoc mechanisms should yield to primary predictive ideology, particularly ideology that unifies formerly disparate phenomena.

An alternative ideology with 3 alternative planet formation mechanisms unifies disparate phenomena under the evolution of a former quadruple star system.

- Triple fragmentation of an original protostar with excess angular momentum forms a hierarchical wide binary star system composed of two close binary pairs: binary-Sun and binary-Companion
- Uranus and Neptune condense planetesimals from a circumbinary protoplanetary disk by gravitational instability (GI) against the binary resonances, forming Uranus and Neptune by ['hybrid accretion' (Thayne Currie 2005)]  And the leftover planetesimals, scattered disk objects (SDOs), are scattered to the scattered disc
- Binary-Sun components isolate outer protostar layers with excess angular momentum during the runaway gravitational collapse forming the second hydrostatic core (SHSC), promoted by nearly-isothermal gravitational collapse mediated by endothermic hydrogen dissociation.  The isolated outer layers themselves undergo GI to form the hot-Jupiter proto-planets, Saturn and Jupiter around the two binary-Sun components.
- Dynamic evolution of the quad system causes binary-Sun to spiral in, leaving Jupiter and Saturn behind in circumbinary orbits, and the stellar components merge at 4,568 Ma, creating a primary debris disk, along with stellar-merger nucleosynthesis r-process radionuclides, principally 26Al and 60Fe and enriching the Sun and primary debris disk in the helium-burning stable isotopes, principally 12C and 16O.
- Asteroids condense by GI against the Sun's magnetic corotation radius, forming Mercury by hybrid accretion.  Chondrites condense in situ against Jupiter's strongest inner resonances.  (Hot classical) Kuiper belt objects (KBOs) condense against Neptune's strongest outer resonances, principally the 3:2 and 1:2 resonances.
- Continued dynamic evolution of the triple star system causes the components of binary-Companion to spiral in, increasing the wide-binary Sun-Companion period at an exponential rate over the next 4 billion years.
- As the solar system barycenter (SSB) between Sun and Companion moves out from the Sun (by Galilean relativity) at an exponential rate over time, it perturbs first Plutinos at 4.22 Ga followed by the cubewanos from 4.1 to 3.8 Ga, causing a double pulse late heavy bombardment of KBOs in the inner solar system.
- The binary brown-dwarf components of former binary-Companion merge at 542 Ma in an asymmetrical merger explosion that gives the Companion escape velocity from the Sun, but the fossil major-axis alignment of detached objects like Sedna and 2012 VP-113 are still visible, although KBOs and SDOs in shorter-period orbits have largely randomized by now.  The loss of the former centrifugal force of the Sun around the SSB caused heliocentric objects into lower orbits, including Venus (in a former synchronous orbit around the Sun) resulting in its slight retrograde rotation.  Earth's orbital upheaval is recorded in the Great Unconformity.
- A 542 Ma secondary debris disk formed from the binary-merger ashes, condensed cold classical KBOs (many of which fragmented to form binaries due to excess angular momentum) including binary Pluto (explaining its geologically-young surface) and Ceres with its low crater count.
New study shows the sun may have snatched Sedna, Biden and other objects away from a neighbor

How 'Starshades' Could Aid Search for Alien Life ... Leonard David -- " The next step in the exoplanet revolution may be an in-space "starshade" that lets alien worlds step out of a blinding glare.

Researchers are testing designs for a starshade, which would fly in formation with a future space-based telescope. The starshade, also known as an "external occulter," would block the light from a star while allowing the scope to spot emissions from much dimmer orbiting planets.

Scientists are conducting desert tests of the technology on Earth. They're using the McMath-Pierce Solar Telescope at Kitt Peak National Observatory in Arizona to model a starshade's ability to help future instruments find and characterize rocky, Earth-like alien worlds.

A starshade may be used on NASA's potential Wide-Field Infrared Survey Telescope (WFIRST), a space-based instrument that would feature a primary mirror 8 feet (2.4 meters) wide, the same size as that of the agency's iconic Hubble Space Telescope.

Several years ago, the U.S. National Reconnaissance Office (NRO) donated two space telescopes to NASA. In 2013, the space agency announced it hoped to use one of these scopes for WFIRST. That move spurred anticipation in the U.S. astronomical community for Hubble-quality imaging over an area of sky 100 times larger than that viewed by Hubble. This version of the mission is called WFIRST-AFTA (for "Astrophysics-Focused Telescope Assets").

The WFIRST-AFTA mission would carry out exoplanet exploration, dark energy research, and galactic and extragalactic surveys. ..."
