Supernova SN 2017eaw and NGC 6946, further follow-up – 22 July 2017
As promised, we continue our follow-up observations of NGC 6946 and its supernova SN 2017eaw. The object was found at mag. 13.1, a little fainter than two weeks earlier. Is this an hint that...
Supernova SN 2017eaw and NGC 6946, an update – 9 July 2017
We continue monitoring supernova SN 2017eaw in the spiral galaxy NGC 6946. Discovered almost two months ago, its brightness is still at its maximum. The image above is the average of twenty, 90-seconds exposures, remotely...
NGC 3938 and supernova SN 2017ein: a new image (22 June 2017)
After our previous visit to the wonderful spiral galaxy NGC 3938 and its supernova SN 2017 ein, we managed to observe it again, finding it significantly brighter. The image above is the average of...
NGC 3191 and the hydrogen-poor superluminous supernova SN 2017egm: 23 June 2017
On 23 May 2017, the Gaia Photometric Science Alerts programme reported the discovery of an apparent supernova, later designed SN 2017egm. It turned out to be the closest hydrogen-poor superluminous supernova (SLSN-I) ever found....
Supernova SN 2017dfc and Messier 63: a new image (28 May 2017)
Do you remember Messier 63 and the SN 2017dfc supernova behind it? At Virtual Telescope we do and are pleased to show this new image, with the transient barely visible, on its way to...
Supernova SN 2017dfc and Messier 63: an image (21 Apr. 2017)
On 20 April 2017, the GAIA mission reported the discovery of a faint transient, not far from the nucleus of the stunning spiral galaxy Messier 63. Later, it was confirmed to be a supernova,...
ASASSN-15lh: un’esplosione cosmica da record piena di sorprese
ASASSN-15lh, l’eccezionale transiente astrofisico di cui Gianluca Masi del Virtual Telescope è co-scopritore, non cessa di stupire. Un nuovo studio suggerisce che all’origine dell’epocale emissione di energia ci sia un evento ancora più estremo e...
Possible supernova AT2016gxp in NGC 51: an image (07 October 2016)
The possible supernova AT2016gxp in NGC 51 was observed via the Virtual Telescope as part of our transient follow-up program. NGC 51 hosting the supernova candidate AT2016gxp, is a lenticular galaxy, placed in the...
Supernova SN 2016gkg in NGC 613: an image – 07 October 2016
Supernova SN 2016gkg was discovered on 20 September 2016 in the barred spiral galaxy NGC 613, at about 65 millions of light years from the Earth. On 7 October 2016, at Virtual Telescope we...
Supernova ASASSN-16fq (2016cok) in Messier 66: an image (03 July 2016)
One month after our last observations, we wanted to image this important supernova again. The image above comes from the average of five, 60-seconds exposures, unfiltered, remotely collected with the PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic...
Probable Supernova ASASSN-16fs in UGC 09523: an image (3 June 2016)
The probable supernova ASASSN-16fs in UGC 09523 was imaged at Virtual Telescope as part of a cooperation with the ASAS-SN survey (ATel 9114). The image above comes from the average of six, 120-seconds exposures, unfiltered, remotely...
Supernova ASASSN-16fq (2016cok) in M 66: an image (01 June 2016)
After our first sight and several cloudy/windy nights, we imaged supernova ASASSN-15fq (aka SN 2016cok), in Messier 66, under fair sky conditions. The image above comes from the average of nine, 180-seconds exposures, unfiltered,...
Supernova ASASSN-16fq (2016cok) in M 66: an image (29 May 2016)
On 28 may 2016, the ASAS supernova survey discovered a possible supernova in the amazing Messier 66 spiral galaxy in Leo; the supernova nature was confirmed a few hours later, suggesting a type IIP...
