© ESA/N. Tr’Ehnl (Pennsylvania State University)/NASAA group of researchers recently observed a mysterious infrared emission coming from near a pulsar in NASA's Hubble Space telescope data. This animation depicts one possible source of the emission: a "fallback disk" or a disk that formed from materials of the parent star falling back into the neutron star after a supernova.
Space is filled with bizarre signals that we scramble to put meaning to -
and now, researchers have detected yet another mysterious signal. This one emanated from near a neutron star, and for the first time, it's infrared.So, what's nearby that could have created the weird signal? Scientists have a few ideas.
When a star reaches the end of its life, it typically undergoes a
supernova explosion- the star collapses, and if it has enough mass, it will form a black hole. But if the star isn't massive enough, it will form a neutron star.
Neutrons stars are very dense and, as their name suggests, are made up mostly of closely packed neutrons. Neutron stars can also be called "pulsars" if they are highly magnetized and rotate rapidly enough to emit electromagnetic waves, according to
Space.com.
Typically, neutron stars emit radio waves or higher-energy waves such as X-rays, according a
statement released by NASA yesterday (Sept. 17). But an international group of researchers from Penn State, the University of Arizona and Sabanci University in Turkey observed something interesting in NASA's Hubble Space Telescope data: a long signal of infrared light emitted near a neutron star, the researchers reported yesterday in
The Astrophysical Journal.
