An article published in “The Astrophysical Journal Letters” reports the detection of radio emissions from the brown dwarf cataloged as WISE J062309.94−045624.6, the smallest known in the field of radio astronomy. A team of researchers used the ASKAP, Australian Telescope Compact Array, and MeerKAT radio telescopes to obtain the measurements necessary to establish the nature of the object. Typically, a brown dwarf smaller than Jupiter doesn’t emit radio waves, making WISE J062309.94−045624.6 an interesting astronomical research target.

An image of part of the Rho Ophiuchi complex captured by the James Webb Space Telescope was chosen to mark the first anniversary of the release of the first official images in astronomy’s new flagship instrument’s science mission. The NIRCam instrument captured details of this giant molecular cloud that forms one of the closest star-forming regions to Earth. Delays and various problems had led to postpone many time Webb’s launch date but in the last year, all the promises of progress in the field of astronomy have been kept and this is only the beginning.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” reports the identification of large amounts of dust from two supernovae in the galaxy NGC 6946. A team of researchers used the James Webb Space Telescope to find traces of dust coming from the supernovae SN 2004et and SN 2017eaw exploiting in particular the potential of the MIRI instrument. The result is the discovery of large amounts of dust among the material ejected from each of the two supernovae and this supports the theory that in the early universe, supernovae played a key role in producing dust.
