NASA continues to look into matters that go beyond the Earth and into space. The agency announced its plans to investigate occurrences happening on the planet’s poles as well as news of a photo taken from the Hubble.
Express reveals that starting this week, NASA will be launching three missions towards the Northern polar cusp and is part of what is called the Grand Challenge Initiative - Cusp. This is in the hope that they can make improvements to the technology that affects the area. University of Alaska professor and space physicist Mark Conde says that the majority of the planet is protected from the solar wind.
However, Conde explains that the area near the poles, in the midday sector specifically, the magnetic field in the area becomes a funnel. This results in solar wind being able to get past the atmosphere. This kind of funnel is known as the polar cusps, which can also interfere with satellite signals along with radio and GPS signals.
These rockets will make 15-minute flights into space before returning back to Earth. Two out of these three missions will be exploring the occurrences happening in the cusp.
Meanwhile, Express also reports that NASA’s Hubble Space Telescope was able to take a photo of a galaxy from 135 million light-years away from Earth. In partnership with ESA or the European Space Agency, this photo was successfully captured.
The telescope was able to take a photo of the NGC 3749 galaxy that is made up of a cluster of stars trillions of miles away from our planet. This particular galaxy is also found in the Centaurus the Centaur constellation and can be seen from the southern skies.
The photo was taken using a process called spectrography. This is how astronomers can determine what is happening within the galaxy. ESA explains that this method is done by spreading light from the galaxy towards a visible spectrum and thus the scientists can be able to look into its properties.
In this case, ESA continues to explain that spectrography helped them see the individual wavelengths coming from NGC 3749. This method also helped them determine the kind of galaxy it is as well as the density and composition.
