It’s invisible, deadly and sucking up every bit of matter in its path. The most massive black hole in the known Universe is headed right toward Earth. What would you see as it started to slurp up the Milky Way Galaxy? What kind of tasty dish would Earth become? And once it’s finished with us, where would it go next? Maybe the Orion Arm? Or perhaps the Oort Cloud?

Where Will We Go After Earth Becomes Uninhabitable?

Where Will We Go After Earth Becomes Uninhabitable?



Ever since humanity discovered that there are other places outside of Earth, we’ve thought about leaving it. On this episode of What If we’re going to do just that. But where would we go? Is building a ring world in space a possibility? Maybe terraforming Venus is our best option for a sustainable life. If we were to leave earth and create something like a ring world, where would we find the materials to do so? And if we lived on Venus, how different would it be from Earth? But before we blast off, why would we ever want to leave?

00:00 Scientists Plan to Leave Earth For Good?
00:48 Earth becomes one of Jupiter’s moons
13:33 Living on a ringworld or terraforming Venus?

From its history, to its potential for being a base for humanity, and more! Join as us as we explore Phobos, Mars’ Moon!

7. History Of Phobos
Phobos was discovered by astronomer Asaph Hall on 18 August 1877, at the United States Naval Observatory in Washington, D.C., at about 09:14 Greenwich Mean Time (contemporary sources, using the pre-1925 astronomical convention that began the day at noon, give the time of discovery as 17 August at 16:06 Washington mean time, meaning 18 August 04:06 in the modern convention).
Hall had discovered Deimos, Mars’s other moon, a few days earlier on 12 August 1877 at about 07:48 UTC. The names, originally spelled Phobus and Deimus respectively, were suggested by Henry Madan (1838–1901), science master at Eton College, based on Greek mythology, in which Phobos is a companion to the god Ares.
Speculation about the existence of the moons of Mars had begun when the moons of Jupiter were discovered. When Galileo Galilei, as a hidden report about him having observed two bumps on the sides of Saturn (later discovered to be its rings).
Hall recorded his discovery of Phobos in his notebook as follows:
“I repeated the examination in the early part of the night of 11th [August 1877], and again found nothing, but trying again some hours later I found a faint object on the following side and a little north of the planet. I had barely time to secure an observation of its position when fog from the River stopped the work. This was at half past two o’clock on the night of the 11th. Cloudy weather intervened for several days.
On 15 August the weather looking more promising, I slept at the Observatory. The sky cleared off with a thunderstorm at 11 o’clock and the search was resumed. The atmosphere however was in a very bad condition and Mars was so blazing and unsteady that nothing could be seen of the object, which we now know was at that time so near the planet as to be invisible.
On 16 August the object was found again on the following side of the planet, and the observations of that night showed that it was moving with the planet, and if a satellite, was near one of its elongations. Until this time I had said nothing to anyone at the Observatory of my search for a satellite of Mars, but on leaving the observatory after these observations of the 16th, at about three o’clock in the morning, I told my assistant, George Anderson, to whom I had shown the object, that I thought I had discovered a satellite of Mars. I told him also to keep quiet as I did not wish anything said until the matter was beyond doubt. He said nothing, but the thing was too good to keep and I let it out myself. On 17 August between one and two o’clock, while I was reducing my observations, Professor Newcomb came into my room to eat his lunch and I showed him my measures of the faint object near Mars which proved that it was moving with the planet.
On 17 August while waiting and watching for the outer moon, the inner one was discovered. The observations of the 17th and 18th put beyond doubt the character of these objects and the discovery was publicly announced by Admiral Rodgers.”
6. Orbits and Rotations
The orbital motion of Phobos has been intensively studied, making it “the best studied natural satellite in the Solar System” in terms of orbits completed. Its close orbit around Mars produces some unusual effects. With an altitude of 5,989 km (3,721 mi), Phobos orbits Mars below the synchronous orbit radius, meaning that it moves around Mars faster than Mars itself rotates.
Therefore, from the point of view of an observer on the surface of Mars, it rises in the west, moves comparatively rapidly across the sky (in 4 h 15 min or less) and sets in the east, approximately twice each Martian day (every 11 h 6 min). Because it is close to the surface and in an equatorial orbit, it cannot be seen above the horizon from latitudes greater than 70.4°. Its orbit is so low that its angular diameter, as seen by an observer on Mars, varies visibly with its position in the sky. Seen at the horizon, Phobos is about 0.14° wide; at zenith it is 0.20°, one-third as wide as the full Moon as seen from Earth.

What If a Rogue Star Collided With the Sun?

What If a Rogue Star Collided With the Sun?

Saturn's Moon Enceladus Could Have Signs Of Life

Saturn's Moon Enceladus Could Have Signs Of Life

From whether the moon known as Enceladus honestly has the potential for life, to what we would do if it honestly has it, and more! Join us as we explore how Saturn’s moon Enceladus could have Signs of life!

As such, as we look at the various planets and even the moons that surround them, we look for anything that could give us a hint that there is indeed life out there. Which brings us to Saturn and one of its many moons.
In 2005, NASA’s Cassini Saturn orbiter discovered geysers blasting particles of water ice into space from “tiger stripe” fractures near Enceladus’ south pole. That material, which forms a plume that feeds Saturn’s E ring (the planet’s second-outermost ring), is thought to come from a huge ocean of liquid water that sloshes beneath the moon’s icy shell. This discovery on its own was special because it meant that there might just be water on this moon, and if there’s water on it, there’s a chance we can colonize the moon as it would allow us to have easy (ish) access to water. But a deeper look at the plume itself revealed things that weren’t expected.
For example, dihydrogen (H2) and a variety of carbon-containing organic compounds, including methane (CH4). The dihydrogen and methane are particularly intriguing to astrobiologists. The H2 is likely being produced by the interaction of rock and hot water on Enceladus’ seafloor, scientists have said,.

NASA’s Curiosity Rover Turns 10: Here’s What It’s Learned (Mars News Report Aug. 5, 2022)

NASA’s Curiosity Rover Turns 10: Here’s What It’s Learned (Mars News Report Aug. 5, 2022)



NASA’s Curiosity Mars rover set out to answer a big question when it landed on the Red Planet 10 years ago: Could Mars have supported ancient life? Scientists have discovered the answer is yes and have been working to learn more about the planet’s past habitable environment.

In this Mars Report, Curiosity Deputy Project Scientist Abigail Fraeman provides an update on the rover’s capabilities a decade after landing in Gale Crater. Now, Curiosity is heading to an area that may help answer how long ancient life could have persisted on the Red Planet as Mars went through significant changes in the climate.

Read more about where Curiosity is currently exploring. Download a poster celebrating Curiosity’s 10 years on Mars here.

Some of the images in the video include color enhancement that exaggerate small changes in color from place to place in the Martian scene. This makes it easier for the science team to use their everyday experience to interpret the landscape. For instance, the sky on Mars would not actually look blue to a human explorer on the Red Planet, but pinkish.
