April's "Pink" Moon I had some other targets in mind when I went out on April 19th, 2019. Seeing conditions were good, wind speeds were low, and there were no clouds in sight so I set out to see M81 and M82 or IC 1396. I was trying to star hop when I noticed bright lights coming from the other side of my house.
"Longevity Gene" - "Species Living More Than 200 Years Evolved Robust SIRT6 Genes" "We have other species that are even longer lived than humans," says researcher Andrei Seluanov at the University of Rochester. Next steps involve analyzing whether species that have longer lifespans than humans-like the bowhead whale, which can live more than 200 years-have evolved even more robust SIRT6 genes.

"The Venus Code" - Unknown Unknowns of Climate Change "Venus is like Earth in so many ways," explains Stephen Hawking. "A sort of kissing cousin. She's almost the same size as Earth, a touch closer to the Sun.
Gaia: The sky is littered with undigested galaxies Sometimes though it may have a dense core which can survive - it's thought that many globulars clusters are in fact cores of old eaten galaxies like this, spat out of the Milky Way like indigestible gum*. But digesting a galaxy takes time. A lot more than seven years, of course; more like hundreds of million of years or more.
Chang'e-4 Updates: Yutu-2 Roves into Overtime, Returns More Images China's Chang'e-4 lander and Yutu-2 rover are continuing to function well and have completed their fourth lunar day since landing on the far side of the Moon on 3 January 2019 this year.
The ghosts of flagships past and future The good news for astronomers is that they are going into their next decadal survey, known as "Astro2020," better prepared than ever.
The Notre Dame fire and the space movement The discussion about the hundreds of millions of dollars and euros that have already been pledged to rebuild the Cathedral of Notre Dame in Paris has ramifications for the space movement.
The Fight Over Who Really Found the First Exoplanet A few years later, astronomers discovered two worlds orbiting another star, a pulsar named PSR 1257+12, and that was that - the era of uncertainty was over and the first exoplanets had been found, destined for the history books. But what if that history is wrong?
20 Things You Didn't Know About Rainbows Everyone sees their own rainbow, and the number of colors in yours may be different from mine.
The Egg ESA: The Egg Nebula is a preplanetary nebula, created by a dying star in the process of becoming a planetary nebula. Planetary nebulas have nothing to do with planets - the name arose when 18th century astronomers spotted them in their telescopes and thought they looked like planets.
ZZ9 Plural Z Alpha The star that we Earthbeings are orbiting, Sol, is located in Sector ZZ9 Plural Z Alpha, which is where we are in the Milky Way. The whole Solar System is also in motion, orbiting around the center of the Milky Way, so I cannot guarantee the accuracy of this photo in your current moment of reality.
Mars Methane Mystery Deepens The methane mystery on Mars just got stranger. New results from ESA and Roscosmos’ ExoMars Trace Gas Orbiter, has unexpectedly not detected methane in the atmosphere of Mars. This result foll…
Exoplanet in the direction of the Southern Hemisphere constellation Reticulum, HD 21749b Exoplanet in the direction of the Southern Hemisphere constellation Reticulum, HD 21749b Earth's perspective is 8.143 is, it really is considerably denser than diamond and titanium, is three times the size of Earth. X-Files. After reading the story, Zeta Reticuli seems a bit creepy now.
NASA astronauts will ride Russian rockets for another year NASA will remain dependent on Russia for the next round of space station rotations.

Science Policy Around the Web - April 19, 2019 Hours after the animals were killed, scientists have partially revived the brains of dead pigs. This contradicts the dogma surrounding death. Cutoff from oxygen, the brain of a mammal is supposed to die after about 15 minutes. The process was thought to be widespread and irreversible: after the cells in the brain die they cannot be brought back.
"Monsters & Dragons?" - Mapping the Terra Incognito of Milky Way's Unseen Far Side "Optically, it's like trying to look through a velvet cloth-black as black can be," says Thomas Dame, Director of the Radio Telescope Data Center at the Harvard-Smithsonian Center for Astrophysics and Senior Radio Astronomer at the Smithsonian Astrophysical Observatory.

Video: Skylight - More Than Meets the Eye What our eyes miss in the sky – stargazing beyond the visible light spectrum Even if you’re able to escape light pollution on a clear night, your view of the Milky Way is still obscured by the Ea…
Hidden Dragon In deep time when the air was fat with moisture and warmth you soared in low gravity, swooped over and along deep Marineris scrabbled amongst rust red rocks, seeking the treasure of tasty morsels. Then, as the air fizzed away to trail behind your little planets orbit and the planetary heart chilled to immobility so you chilled and slowed.
