View astrophysicsman's Instagram NGC 3314 is a pair of overlapping galaxies located some 117-140 light years away in the constellation Hydra. Although these galaxies may appear to be interacting, their actually not. The galaxies are too far apart and therefore do not interact with each other. This is actually a very unique alignment, and has given astronomers the opportunity to study and measure the properties of interstellar dust in the face-on foreground galaxy which appear dark against the background galaxy. 
In March 2000 while observing NGC 3314 astronomers spotted a green-like star. Astronomers have theorized that this may have been a supernova explosion, however, it still remains unknown.

View astrophysicsman's Instagram Are we alone in the universe? Is Earth the only habitable world in the universe? The answer to these questions may be closer than we think, literally. When we talk of other life forms in the universe we usually think of other planets light years away that contain life. However, new findings are showing that there may be other habitable worlds within our own solar system. Europa, Enceladus, Titan, and Mars all show promise. 
Europa is one of the four Galilean moons of Jupiter. The Voyager flybys of the moon showed evidence Europa harbours a subsurface ocean, which is home to organic compounds. Water and organic compounds sounds extremely promising. Europa, however, isn't the only world where water and organic compounds exist, or use to exist. Saturn's moon Enceladus, like Europa, contains a subsurface ocean of liquid water rich in organic compounds. Mars is known to have once had rivers, lakes, and perhaps even oceans of liquid water across its surface. Mars also contains organic compounds. Life may not exist there anymore, but maybe it once did. Titan, however, is a different story. Although Titan has hydrocarbons and other organic compounds, it doesn't have liquid water. It still has a liquid on its surface, however. This liquid isn't water, it's liquid methane and ethane. If life exists on Titan it will be far different than any life forms we've encountered. 
Are we alone? New findings even within our own solar system suggest that we are in fact not alone. However, any life forms in our solar system are likely going to be very simple organisms, likely a kind of bacteria. What about complex life? We may have to look deeper into space to find answers.

View astrophysicsman's Instagram The first step to finding alien life is to look for an area where it could potentially exist. The Kepler space telescope has shown that their could be over 40 billion Earth-like planets in our galaxy alone. Astronomers have discovered a few of these planets. If life exists on any of these planets how could we know? Some are hundreds to thousands of light years away, so we obviously can't go there ourselves. So how can we detect alien life from Earth? One method which has been used on gas giants around other stars is to examine the spectrum of the planet. How? Planets are so small and dim how could we possibly study their spectrum? So far astronomers have only been able to study the spectrum of giant gas planets around other stars, technology simply isn't advanced enough yet to examine the spectrum of smaller rocky worlds. How does examining the spectrum of a planet help us determine whether life exists there or not? Simply find large amounts of oxygen like the Earth's atmosphere. The oxygen in our atmosphere is primarily due to life. If we found large amounts of oxygen in another planets atmosphere it would be evidence of life. If you also found the spectrum of methane within the atmosphere, in small amounts, it would also offer evidence of life. How do we know that large amounts oxygen and lower amounts of methane in an atmosphere mean life exists there? Because that's exactly what the Earth's atmosphere contains. And both the methane and oxygen are produced by living organisms. So if scientists ever discovered large quantities oxygen and small quantities of methane in a planets atmosphere it would be evidence of alien life.

View astrophysicsman's Instagram It's interesting that the life and death of a star is determined by the stars mass. Massive stars, such as O-type stars, tend to live relatively short lives (in astronomical terms). Massive stars such as these live only a few hundred millions years until they die in a supernova explosion. Why is this? Why is it that massive stars live short lives? Because the star is so massive it has a very high temperature and tends to burn its nuclear fuel at a fairly fast rate. The hydrogen within the star is fused into helium at a much faster rate in higher mass stars than lower mass stars. Lower mass stars, such as our sun, can continue to burn nuclear fuel in their cores for billions of years, and even lower mass stars, such as M stars, can live for trillions of years until they burn all their nuclear fuel. These stars not only live differently, but will also die differently. Massive stars will die in massive supernova explosions and will form either a neutron star, a pulsar, or a black hole depending on its mass. Lower mass stars will die a much quieter death. Rather than bursting apart, lower mass stars will simply expand and eventually fade away, forming a planetary nebulae with a white dwarf at its centre.
