SDO: Coronal hole Feb 2017

Seven years of Solar Dynamics

It seems like only yesterday that I was noting First Light on Nasa’s Solar Dynamics Observatory [SDO], and the early hours of this morning for ‘three years in three minutes‘ and ‘SDO Year 4‘.  In fact the SDO was launched on 11 Feb 2010, with First Light in April of that year. [Seven long years… more…

Another view…

Vote… don’t vote…  In the meantime, here’s another in an occasional series of wondrous views from the International Space Station, via the Nasa Crew Earth Observations videos – Sunglint over the Ocean.  [Video courtesy of the Earth Science and Remote Sensing Unit, NASA Johnson Space Center] This video was taken by the Expedition 47 crew more…

New Horizons Charon

New Horizons: Live Briefing

Having survived yesterday’s fly-by, follow the live-briefing from the Nasa New Horizons mission to Pluto as they reveal the first hi-resolution images from the dwarf planet system nearly 5 billion km away. Adds The big news is that Pluto, and Charon, may still be geologically active. There are 3,500metre (11,000feet) high water-ice mountains on the more…

Showalter (SETI Institute)]   Travelling at 14km/s, New Horizons’ swift fly-by of the dwarf planet is scheduled to take place on Tuesday 14 July, at more…

ISS Night-time Compilation

A brief musical interlude, accompanied by a selection of wondrous time-lapse videos, old and new, from the International Space Station, by NASACrewEarthObs.  Full-screen mode recommended.  Enjoy! [Credit: Image Science and Analysis Laboratory, NASA Johnson Space Center.] The final video clip shows the surprisingly robust sun-grazing Comet Lovejoy as it emerged triumphant from its close encounter with Sol in December 2011.

Hubble Space Telescope 25th Anniversary Image - Westerlund 2

Raise a glass to Hubble! – Redux

The Hubble Space Telescope celebrates its 25th Anniversary in space today, 24th April, with the release of this wondrous image of the giant star-cluster, Westerlund 2, in the stellar nursery, Gum 29, located 20,000 light-years away in the constellation Carina.  [Image credit: Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), A. Nota (ESA/STScI), and the Westerlund more…

swap solar eclipse 2015_03_20

In case you missed the eclipse…

Or, like me, cloud cover obscured the solar eclipse of 20 March 2015.  Here’s probably the best view of this morning’s event, from ESA’s Sun-watching Proba-2 mini-satellite.  [Image credit: ESA/ROB] And via ESA on YouTube. As Europe enjoyed a partial solar eclipse on the morning of Friday 20 March 2015, ESA’s Sun-watching Proba-2 minisatellite had a ringside more…

Solar Eclipse Belfast UK 2015 Mar 20

Stargazing the 20 March 2015 Solar Eclipse

The BBC’s Stargazing Live returns tonight, 8pm BBC 2, with three consecutive nights of live programmes to coincide with the total solar eclipse on Friday 20 March 2015.  [It is an annual series! – Ed].  Stargazing Live is, yes.  Not necessarily total solar eclipses, though.  And this solar eclipse is the only one, total or otherwise, to be more…

Cassini image of Earth in Saturn's rings

“There’s no place like home…”

I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home.  I don’t think it encouraged a proper sense of perspective…  But the resultant image is stunning. [Image Credit: NASA/JPL-Caltech/Space Science Institute] It’s not the first time Cassini has looked home.  Nor more…

Voyager

Voyager: “We are approaching the solar system’s final frontier”

Here’s a short informative video from Science at Nasa on the indications that Voyager 1 is about to enter into the vastness of interstellar space.  (Image credit: NASA/JPL-Caltech) Space, remember, is very very big. And on that note, because I can, here again is some wondrous time-lapse video of the night-sky above the ESO Very Large Telescope array [VLT], in more…

Transit of Venus 2012: “marvel at the solar system in motion”

As I mentioned back in March, tonight one of the rarest predictable astronomical events will occur – a transit of Venus.  [I’m washing my hair! – Ed]  What hair?  ANYhoo… Since the invention of the greatest human innovation, the telescope, at the beginning of the 17th century, not by Galileo, there have been only 7 such more…

Aurora Borealis over Europe

Another wondrous view of the Aurora Borealis as captured by the crew of the International Space Station.  This time as a backdrop to the equally wondrous sight of Ireland and the United Kingdom under night-time conditions [0-18s].  Video via NasaCrewEarthObs. This video was taken by the crew of Expedition 30 on board the International Space Station. The more…

Galactic plane with close-up on centre

“A billion stars revealed”

A stunning image was unveiled last week at the UK-Germany National Astronomy Meeting NAM2012 in Manchester. [All images courtesy of Mike Read (WFAU), UKIDSS/GPS and VVV] The BBC’s Spaceman, Jonathan Amos, helpfully provides this combination image, with a partial zoom-in on the Galactic center. But to really appreciate the scale and detail of the image you more…

“awe, curiosity, wonder, joy, amazement”

After a brief scientific explanation of the phenomena, this video from LittleSDOHMI delivers some wondrous recent views (March 3, 4 and 10) of the Aurora Australis from the International Space Station.  With music! [Video credit: NASA ISS/JSC/ Science@NASA] And here are those stunning clips by themselves. [All videos courtesy of the Image Science & Analysis Laboratory, more…

“…and marvel at the solar system in motion”

Here’s a date to mark in your diary [really? – Ed].  On the 5/6 June this year one of the rarest predictable astronomical events will occur – a transit of Venus.  [Can’t wait… – Ed]  Since the invention of the greatest human innovation, the telescope, at the beginning of the 17th century, not by Galileo, more…

WISE mosaic of entire infrared sky

The Universe at a glance…

Well, several glances actually…  As spotted by the Guardian blog’s Tom McCarthy, NASA has released a new atlas and catalog of the entire infrared sky “showing more than a half billion stars, galaxies and other objects captured by the Wide-field Infrared Survey Explorer (WISE) mission.”  And an impressive view it is.

Opportunity's Eighth Anniversary View From 'Greeley Haven'

“Opportunity on Mars – 8 years and counting!”

Nasa’s Mars Exploration Rover Opportunity landed in Eagle Crater on Mars on Jan. 25, 2004, Universal Time, three weeks after its rover twin, Spirit, had landed halfway around the planet.  Opportunity completed its three-month prime mission in April that year, everything else has been bonus, extended missions.  Spirit is no longer with us.  But Opportunity carries more…

Stargazing, and [exo]planet hunting…

The last three nights saw the return to BBC2 of popular astronomy show Stargazing Live – presented by Brian Cox and Dara O’Briain.  Hopefully it will become, at least, an annual fixture. [Image credit: ESO/Y. Beletsky] The three hour-long programmes are still available, for now, on the iPlayer.  The entertaining ‘after-show’ shows, Back to Earth, appears to more…
