Tests are being done on the worms to understand how their biological processes can be affected in a micro-gravity, or zero gravity environment. Researchers hope to use what they learn about the effect on the worms to hypothesize, or build models, on how spaceflight might affect humans. This knowledge can then hopefully be used to prepare humans for the long flight to Mars. Although the worm's biology is very simple in comparison to the comlex biology of a human, worms and humans share many of the same biological processes. Another advantage of studying the worms is that their lifespan is about 2 -3 weeks, so that s cientists can get a gd ideaa on the affects of microo-gravity on the whole lifetime of a creature. This knowledge can then be applied to humans, in predicting how affects a long spaceflight would have on the human anatomy. All 959 cells of a worm are visible through a microscope, and worms have a nervous system, a brain, muscles and a gut. It exhibits behavior and is capable of rudimentary learning. It produces sperm and eggs, and reproduces, although normally as a hermaphrodite. After reproduction, the worm gradually ages, loses vigor and finally dies.

Ice-cream and pizza are being delivered to the International Space Station (ISS). YUM. Venus and Jupiter were aligned and were very close to each other in the morning sky on November 13, 2017. Also, astronomers are using pulsars to track G Waves. Gravitational waves are ripples in space-time. They are created from the collision of black holes or neutron stars, amongst other things. They occur from masses accelerating in space. G waves also result from black holes or neutron stars as they do they dance around each other, before they merge. Most galaxies harbour super-massive black holes at their centers. When 2 galaxies merge (that have super-massive black holes) they produce low-frequency G waves. These G waves from the collision of 2 super massive black holes have not yet been detected. Remember, super massive black holes can have the mass of millions or billions of solar masses. To try to find these kind of G waves, astronomers are using pulsars to help. Pulsars are neutron stars that spin. They spin so fast, that they emit many pulses of radio waves each second. Some pulsars can spin hundreds of times each second. The North American Nanohertz Observatory for Gravitational Waves (NANOGrav), is one group using pulsars to search for G waves. A pulsar, or pulsar timing array, emits radio waves in such a predictable pattern, that if a G wave hits the pulsar, then the distortion in space-time of the G waves can be measured from the distortion, or the offset, of the pulse from the pulsar. Observatories like LIGO detect G waves in the seconds just before 2 black holes or 2 neutron stars merge, but it can take millions of years for 2 BHs or 2 NSs to merge. While they are engaged in this cosmic death dance around each other for millions of years before they merge, G waves are emitted.

Ice-cream and pizza are being delivered to the International Space Station (ISS). YUM. Venus and Jupiter were aligned and were very close to each other in the morning sky on November 13, 2017. Also, astronomers are using pulsars to track G Waves. Gravitational waves are ripples in space-time. They are created from the collision of black holes or neutron stars, amongst other things. They occur from masses accelerating in space. G waves also result from black holes or neutron stars as they do they dance around each other, before they merge. Most galaxies harbour super-massive black holes at their centers. When 2 galaxies merge (that have super-massive black holes) they produce low-frequency G waves. These G waves from the collision of 2 super massive black holes have not yet been detected. Remember, super massive black holes can have the mass of millions or billions of solar masses. To try to find these kind of G waves, astronomers are using pulsars to help. Pulsars are neutron stars that spin. They spin so fast, that they emit many pulses of radio waves each second. Some pulsars can spin hundreds of times each second. The North American Nanohertz Observatory for Gravitational Waves (NANOGrav), is one group using pulsars to search for G waves. A pulsar, or pulsar timing array, emits radio waves in such a predictable pattern, that if a G wave hits the pulsar, then the distortion in space-time of the G waves can be measured from the distortion, or the offset, of the pulse from the pulsar. Observatories like LIGO detect G waves in the seconds just before 2 black holes or 2 neutron stars merge, but it can take millions of years for 2 BHs or 2 NSs to merge. While they are engaged in this cosmic death dance around each other for millions of years before they merge, G waves are emitted. LIGO cannot detect these types of G waves, but astronomers believe that they can detect these types of G waves. When 2 galaxies merge, their black holes (BHs) will usually merge millions of years later. They will emit G waves while they are doing their death dance around each other, and astronomers believe they can detect the G waves that are emitted in this process.]]>1381cleanfullhttps://www.spreaker.com/episode/gravitational-lensing-monitoring-antarctic-penguin-populations-and-what-provides-heat-for-enceladus-subsurface-ocean--23524915NASA Satellites are monitoring Antarctic Penguin population.

Also, in another region of our Solar System, the Mars Reconnaissance Orbiter (MRO) is exploring a region called, "Noctis Labyrinthus".

The image is magnificent, and can be found on https://www.nasa.gov/image-feature/jpl/pia21585/a-mesa-in-noctis-labyrinthus. Another image from MRO shows a hill on Mars, on the South Pole layered deposits. The hill protects the icy layers from erosion, so the image shows the hill with beautiful spiral patterns. In another finding from MRO, over 500 new impact events have been exposed from before and after images of the Southern Middle Latitudes.

On April 17, 2016, the New Horizons spacecraft (NH) will have reached its halfway point on its flight from Pluto, to its next target in the Kuiper Belt, 2014 MU69 (486.19 million miles from Pluto). When NH does reach 2014 NMU69, it will become the most distant world ever explored in our Solar System. NH is actually slowly down slightly due to the gravitational pull of the Sun. It will therefore reach its midpoint in distance 5 days before it reaches its midpoint in time. And, to add more intrigue to this unfolding drama, NH will also be asleep on April 7, before it reaches the midpoint. This will be done to preserve the systems on the spacecraft. The spacedraft will be put in hibernation for 157 days, but it needs the time off. NH would have been "awake" for 1 and 1/2 years, since December 2014. In that time period, NH flew by Pluto, relayed data back to Earth for 16 months, and also studied a dozen other Kuiper Belt Objects (KBOs). The busy little spacecraft has also studied the outer reaches of the heliosphere (the Sun's atmosphere), and the Kuiper Belt's dusty, ionicly charged environment. Another interesting fact: a signal sent between NH and Earth takes 5 hours and 20 minutes (at the speed of light) to travel the 3.5 billion mile distance between Earth and the New Horizons spacecraft. Now, off to Saturn. Cassini is preparing for its Grand Finale at Saturn, where it will dive between Saturn and its rings, then burn up in Saturn's atmosphere. It will actually go through a total of 22 dives before its grand finale. Cassini has been in the Saturn system for 13 years, and since then it has learned much about things like the moon Enceldus, its icy surface, and its sub-surface ocean, and also about the moon Titan, and its liquid methane seas. With the ocean of information it has gained in this 13 years, mission scientists are using all this information to make the final dive very purposeful. During the final plunge, Cassini will sample Saturn`s atmosphere, sample particles from the rings, and relay back to Earth the closest ever pictures of Saturn, its clouds, and its inner rings. The duties that the robotic probe on Cassini will be assinged to undertake will be downloaded to the probe in what is called a sequence, on April 11. Cassini will study the moon Titan one last time, on April 22, then will carry out other experiments, all in anticipation for its grand finale dive on September 15.

The Goddard Institute for Spaces Studies in New York has presented data that suggest the past three Octobers, 2014, 2015 & 2016, have seen the highest global temperatures on record for that month. Global temperatures have been monitored for 136 years, and October 2016 was the second warmest October on our planet for the past 136 years, the warmest October happening in October 2015. The 10 warmest Octobers on record have also been recorded after the year 2,000. Goddard scientists also suggest that the study of trends are more important than just year-to-year data. Data after 2,000 therefore suggest that our planet is, indeed, warming up.
Perhaps tied in with these findings are other findings relating to a cyclone in the Arctic. In their monitoring of our planet, NASA scientists have detected the damage done to the ice pack in the Arctic by a cyclone that passed through that region in late December 2015. The cyclone brought a lot of humidity and an increase in air temperature of 10 degrees F to the air over the Arctic. The warm air thinned and shrunk the sea ice cover in the Arctic, at a time when ice there should have been growing stronger and thicker. The warm air from the storm, and the storm itself, compacted the ice pack, pushing it further North.

Astronomers classify AGN into two main types based on the properties of the light they emit. One type of AGN tends to be brighter than the other. The brightness is generally thought to depend on either or both of two factors: the AGN could be obscured by surrounding gas and dust, or it could be intrinsically dim because the rate of feeding of the supermassive black hole is low.

Some AGN have been observed to change once between these two types over the course of only 10 years, a blink of an eye in astronomical terms. However, the AGN associated with the galaxy Markarian 1018 stands out by changing type twice, from a faint to a bright AGN in the 1980s and then changing back to a faint AGN within the last five years.

When humans went to the Moon, for example, the spacecrafts did not travel very fast: in relative terms that is. When travelling to Mars, the spacecrafts will have to travel at a far greater speed, because Mars is so much farther from Earth than is the Moon. Since the spacecraft's speeds will be much higher, a lot more of something will be needed to brake the spacecraft and slow it down enough so it can begin to orbit Mars. Can the firing of rockets brake the spacecraft enough? Maybe not, because that would require too much fuel, and these spacecrafts cannot carry endless supplies of fuel.
