Messier 101 and a (likely) supernova impostor
Messier 101 surely is one of the most beautiful spiral galaxies out there. Because of its relative proximity (about 20 millions of light years), its face-on geometry and the elegance of its arm, the...

IC 983, NGC 5490 and PSN J14095513+1731556: an image (19 Feb. 2015)
Recently, while following-up a recently discovered optical transient, PSN J14095513+1731556 – turned out to be a supernova – we spied a nice spot of the sky where, all around the supernova and its host galaxy (NGC...
Supernova PSN J14095513+1731556 in NGC 5490: an image (18 Feb. 2015)
The Universe is so huge that ever the most active observers are continuously facing new gems floating in the outer space. This also happens every time you slew your telescope to a new object,...
Supernova ASASSN-14lp in NGC 4666: an image (21 Dec. 2014)
On 9 Dec. 2014 the All Sky Automated Survey for SuperNovae (ASAS-SN), using data from the quadruple 14-cm “Brutus” telescope in Haleakala, detected a probable supernova in NGC 4666. This transient was designed ASASSN-14lp. Later, it was...
Supernova SN 2014dt in Messier 61: a new image (21 Dec. 2014)
After almost two months, at Virtual Telescope we visited supernova SN 2014dt and its hosting galaxy Messier 61 again. The picture comes from the average of two, 180-seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E...
Four Supernovae in Four Messier Galaxies: SN 2014J (M82), SN 2014L (M99), SN 2014bc (M106) and 2014dt (M61)
The recent supernova in Messier 61 is the latest member of a very special and very small group, the one including all the supernova events happened in 2014 in a Messier galaxy. So far,...
Possible Supernova PSN J02183806+3336583: an image (02 Nov. 2014)
This image of the possible Supernova PPSN J02183806+3336583 in the PGC 2035709 galaxy comes from the average of five, 120-seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The supernova was estimated at...
Possible Supernova PSN J02262331+2739348: an image (02 Nov. 2014)
This image of the possible Supernova PSN J02262331+2739348 in the UGC 1899 galaxy comes from the average of five, 120-seconds exposures, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The supernova was...
Bright supernova MASTER OT J120451.50+265946.6 in NGC 4080: an image (31 Oct. 2014)
This is a good season for reasonably bright supernovae. Just before SN 2014dt in Messier 61 was discovered, another bright supernova has been found in NGC 4080, named MASTER OT J120451.50+265946.6 after the survey which...
Supernova SN 2014dt (= PSN J12215757+0428185) in Messier 61
Updates: this transient has been spectroscopically confirmed as a peculiar type Ia supernova and it is now officially named SN 2014dt, after the CBAT issued the CBET 4011 (login required) Circular, including our observations! Six...
PGC 13880 and PSN J03481978+7007545: an image
There are so many wonders out there, in the Universe, that is simply impossible for us to see all of them. To the point that sometimes we unexpectedly discover something very beautiful just by...
Messier 82 and Supernova SN 2014J: a new image and animation (24 Aug. 2014)
For sure, supernova SN 2014J in M82 has been one of the most important seen in recent years. At Virtual Telescope we tracked it since its discovery and wanted to see how bright it...
Supernova SN 2014bv ( = PSN J12243098+7532086) in NGC 4386: image and spectroscopy
Updates (21 June 2014): the Central Bureau for Astronomical Telegrams (CBAT) issued CBET 3911 (subscription required), were this object is officially designed SN 2014bv. The mentioned CBET reports our observations: “Additional CCD magnitudes for 2014bv: […] May 19.913,...
Messier 82 and SN 2014J: a new image (4 June 2014)
After more than four months since it was discovered, supernova SN 2014J in Messier 82 was observed again by the Virtual Telescope. The star looked much dimmer than last time we visited it. Above is...
