Ceres and Vesta close conjunction: image and podcast (5 July 2014)

Ceres and Vesta close conjunction: 5 July 2014

Ceres and Vesta close conjunction: 5 July 2014

Finally, at Virtual Telescope we observed the dwarf planet (1) Ceres and the asteroid (4) Vesta at their minimum angular distance (10 arcminutes, 1/3 of the angular size of the full Moon disk), sharing the sight with several thousands of people from all around the globe, who joined our live coverage of the conjunction.

Above is a spectacular image, coming from the average of three, 15-seconds exposures, then superimposed after registering them against the stars. As both Ceres and Vesta were moving across the stars, they changed position from one image to the other, this explaining why they show as “triple” objects (three images!). All the images were collected remotely with the 17″ robotic unit part of the Virtual Telescope. There was a very strong interference by the Moon, less than 10 deg apart.

Below is a podcast coming from the live coverage.

Ceres and Vesta close conjunction: a new image (4 July 2014)

While Ceres and Vesta prepare their closest conjunction. at Virtual Telescope we imaged this unusual couple again.

Above is an image showing the dwarf planet Ceres and the asteroid Vesta less than 12 arcminutes apart, with Vesta being clearly brighter than the other.

The image above was remotely taken with the 17″ robotic unit part of the Virtual Telescope.

Ceres and Vesta close conjunction: an image (3 July 2014)

Next 5 July, we will show live the amazing, rare conjunction between the dwarf planet Ceres and the asteroid Vesta. While waiting for this big show, we captured this view already showing the couple so close in perspective.

The image is a single 60-seconds exposure, remotely taken with the 14″ robotic unit part of the Virtual Telescope. The field of view is 10′x15′, so it is clear that the two bodies are in a patch of sky smaller than the angular size of the Moon.

A satellite trail is also visible, enriching the view.

Ceres and Vesta meet in the sky: online observing session (5 July 2014)

*** See Ceres and Vesta live here! ***

Next 5 July 2014, the dwarf planet Ceres and the asteroid Vesta will apparently meet in the same spot in the sky: they will be less than 10 arc-minutes apart, being an easy target for small scopes. Their last conjunction was in 1996, but at that time they were more than two degrees apart.

At Virtual Telescope we planned to show live this rare event, for free, thanks to our robotic telescopes and our live webTV.

The online, free session is scheduled for 5 July 2014, starting at 20:00 UT.

Potentially Hazardous Asteroid 2014 HQ124: podcast and image (10 June 2014)

Potentially Hazardous Asteroid 2014 HQ124: 10 June 2014

Potentially Hazardous Asteroid 2014 HQ124: 10 June 2014

On 10 June 2014 at Virtual Telescope we shared live, online, the potentially hazardous asteroid 2014 HQ124, a couple of days after its close encounter with the Earth. The session was a big success, with the asteroid beautifully visible and perfectly tracked by our systems.

Above is an image coming the live show, captured with the 17″ robotic unit, where the asteroid is visible in the center: the telescope was tracking 2014 HQ124, so stars are apparently sliding.

Below is the full podcast from the online event

Potentially Hazardous Asteroid 2014 HQ124 close approach: online observing session (10 June 2014)

Next 8 June 2014, at 05:57 UT, the Potentially Hazardous Asteroid (PHA) 2014 HQ124 will make a close encounter with the Earth. This ~320 meters large asteroid will reach a minimum distance of 1.3 millions of km from us, so really no risks of collisions, just a nice chance for spotting this little body in the sky.

The Virtual Telescope Project will offer a live, online event sharing real-time images of 2014 HQ124 with live commentary by our scientific staff.

The online, free session is scheduled for 10 June 2014, starting at 20:00 UT.

Near-Earth Asteroid 2014 KH39 very close encounter: an extreme image (3 June 2014)

Near-Earth Asteroid 2014 KH39 very close encounter: 3 June 2014

Near-Earth Asteroid 2014 KH39 very close encounter: 3 June 2014

On the evening of 3 June 2014, at Virtual Telescope we hosted a live, online observing session to show the very close approach of the ~25 meters large near-Earth asteroid 2014 KH39. At 20:07 UT, this rock reached a minimum distance from us of 430.000 km, 1.1 times the average distance of the Moon. As clearly stated since the discovery of this object (24 May 2014 by the Mt. Lemmon Survey in Arizona), there were NO risks of collision with the Earth.

The live coverage offered by the Virtual Telescope made possible to almost 20.000 individuals from 128 Countries to have a look. The live event covered the very moment of the closest approach.

Above is an image coming from a single, 120-seconds exposure,  taken at the minimum distance time, during the show. It was captured with the PlaneWave 17 robotic unit, with the Paramount ME mount tracking the fast (316″/minute !) apparent motion of 2014 KH39, which was less than 35 deg above the northern horizon and fainter than magnitude 17.7. This image is one of the most amazing, possible proofs of performance a telescope can ever provide. We’re proud!

Below is the podcast of the whole event, if you missed this thrilling encounter, so beautifully covered by the Virtual Telescope Project.

Acknowledgements: this event was a joint effort with Ansa Scienza & Tecnica. The Virtual Telescope also thanks the space.com, Universe Today and EarthSky teams for featuring the event.

WE also wish to thank the technological partners of the Virtual Telescope Project.

Near-Earth Asteroid 2014 KH39 getting closer: a new image (2 June 2014)

Near-Earth asteroid 2014 KH39: 2 June 2014

Near-Earth asteroid 2014 KH39: 2 June 2014

At  the Virtual Telescope, we visited the near-Earth asteroid 2014 KH39,  while it approaches us for the close, but safe tomorrow’s close encounter.

This  is a single 300-seconds exposure, taken with the main PlaneWave 17 robotic unit: the Paramount ME tracked the apparent motion (55″/minute, almost four times faster than yesterday) of the object, resulting in a sharp asteroid (sitting in the center of the frame) and trailed stars. At the imaging time, the ~25 meters large asteroid 2014 KH39 was at about 1 millions of km from us (half of yesterday’s distance).

This perfect image shows the amazing performances of the telescopes part of the Virtual Telescope.

Near-Earth Asteroid 2014 KH39: an image (1 June 2014)

Near-Earth asteroid 2014 KH39: 1 June 2014

While approaching our planet, the near-Earth asteroid 2014 KH39 was imaged again via the Virtual Telescope.

Above is a single 300-seconds exposure, taken with the main PlaneWave 17 robotic unit: the Paramount ME tracked the apparent motion (16″/minute) of the object, resulting in a sharp asteroid (marked by the arrow in the center) and trailed stars. At the imaging time, the ~25 meters large asteroid 2014 KH39 was at about 2 millions of km from us. A satellite trail is also visible.

Next 3 June 2014, at 20:07 UT, the 25-meters large asteroid 2014 KH39 will made a very close approach with the Earth, reaching a minimum distance of less than 440.000 km, that is 1.14 lunar distances.

Of course, this is a very safe distance, but still a very spectacular circumstance, so  the Virtual Telescope Project will offer a live, online event sharing real-time images of 2014 KH39 with live commentary by our scientific staff.

The online, free session is scheduled for 3 May 2014, starting at 19:45 UT.
