The human journey to the beginning of space and time recently viewed the closest Type IA supernova found during modern times. The new supernova, called SN 2014J, is about 12 million light-years distant in the Cigar Galaxy M82, which is in the constellation Ursa Major.

NASA’s Spitzer Telescope, along with legions of ground-based and orbiting telescopes, are currently peering directly into the heart of this supernova. Spitzer can peer through the dust and other debris between Earth and the new supernova, using specially designed infrared detectors and cameras. Combined with the data from the legions of ground-based and orbiting telescopes, NASA should be able to provide us with a stunning view of SN 2014J.

“At this point in the supernova’s evolution, observations in infrared let us look the deepest into the event,” said Mansi Kasliwal, Hubble Fellow and Carnegie-Princeton Fellow at the Observatories of the Carnegie Institution for Science and the principal investigator for the Spitzer observations. “Spitzer is really good for bypassing the dust and nailing down what’s going on in and around the star system that spawned this supernova.”

First viewed on January 21, 2014, by students and staff from University College London, SN 2014J is a Type IA supernova, which astronomers believe is a binary star system. Type IA supernovae are thought by astronomers to occur due to two possible scenarios. Either a white dwarf star pulls matter from a companion star until it reaches a threshold and explodes, or two white dwarf stars slowly spiral inward toward each other until they collide, creating a supernova explosion.

Type IA supernovae are important because they explode with almost the same amount of energy and with a uniform peak brightness. Astronomers use Type IA supernovae as standard candles, which allows them to measure distances to nearby galaxies more accurately. Further study of supernova SN 2014J will help astronomers understand the processes producing this type of supernova and determine interesting facts concerning other types of supernovas.

NASA astronomers are currently using the Hubble Space Telescope, Chandra X-Ray Observatory, Nuclear Spectroscopy Telescope Array (NuSTAR), Fermi Gamma-ray Space Telescope and Swift Gamma Ray Burst Explorer to take a closer look at supernova SN 2014J.

Astronomers Bring Another Strange Creature to the Pulsar Zoo

Neutron star SGR 0418+5729 is a slowly rotating neutron star astronomers recently added to the Pulsar Zoo

Neutron star SGR 0418+5729 shows off

Astronomy News – The human “Journey to the Beginning of Space and Time’ discovered another neutron star on June 5, 2009, that’s currently keeping astronomers and space scientists busy looking into the unusual properties of this newest member of the pulsar zoo. Astronomers using NASA’s Chandra, Swift and Rossi X-ray observatories, the Fermi Gamma-ray Space Telescope and ESA’s XMM-Newton telescope have been taking a look at this slowly rotating neutron star with an ordinary surface magnetic field as it gives off x-rays and gamma rays. Astronomers think the facts they have collected during their study of neutron star SGR 0418+5729 could indicate the presence of an internal magnetic field much more powerful than the surface magnetic field of this pulsar. This has definite implications in relation to the evolution of the most powerful magnets we have observed during the human “Journey to the Beginning of Space and Time” and astronomers are now delving into the mysteries they see within this neutron star to determine the facts.

Another strange neutron star

Astronomers looking at neutron star SGR 0418+5729 think this pulsar is one of a strange breed of neutron stars they refer too as magnetars, which normally have strong to extreme magnetic fields 20 to 100 times above the average for galactic radio pulsars they have viewed in the universe. What really has astronomers viewing SGR 0418+5729 scratching their heads is the fact that over a 490 day period of observing this pulsar astronomers saw no detectable decrease in this neutron stars rotational rate.

Astronomers think that the lack of rotational slowing of this neutron star could mean that the radiation of low-frequency waves is pretty weak, which leads them to believe the surface magnetic field of this pulsar must be quite a bit less powerful than normal. This conclusion gives astronomers another puzzle to solve, since with this thought astronomers are wondering where the energy for this neutron stars power bursts and x-ray emissions come from.

Does the power and energy creating this neutron stars power bursts and x-ray emissions originate in the twisting and amplifying of this pulsars internal magnetic field in the chaotic interior of this neutron star?

Present theories on this indicate that astronomers believe that if the internal magnetic field becomes ten or more times stronger than the surface magnetic field, the twisting or decay of the magnetic field could lead to the production of steady and bursting x-rays through the heating of the pulsar’s crust or the acceleration of particles in the magnetic field.

The question astronomers want to answer now is how large can the imbalance between the surface and interior magnetic fields be? If further observations indicate that the surface magnetic field limit is pushed too low, then astronomers will have to dig a little deeper into SGR 0418+5729 to find out why this neutron star is rotating slower.
