In case you missed the eclipse…

swap solar eclipse 2015_03_20

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…

Stargazing the 20 March 2015 Solar Eclipse

Solar Eclipse Belfast UK 2015 Mar 20

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…

Dawn over Ceres

Dawn at Ceres

On Friday afternoon [GMT], ahead of Ireland cricketers’ epic encounter with Zimbabwe, Nasa’s Dawn spacecraft became the first man-made object to go into orbit around a dwarf planet – Ceres, at 950km across, the largest object in the main asteroid belt. [Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA] From the associated text The slim crescent of Ceres smiles back as the more…

Solar Dynamics Observatory: Year 4

Four years after its work began, and following last year’s three years in three minutes, Nasa have released another wondrous short video of a year of selected solar activity as viewed by the Solar Dynamics Observatory. Video via Nasa Goddard.  Full-screen viewing recommended.  Stunning.

“an unforgettable journey across the Red Planet.”

HRSC on Mars Express - Valles Marineris

Curiosity may have been on the surface of Mars for over a year, but ESA’s Mars Express has been in orbit around the Red Planet for almost a decade.  It’s one of a number of ways Mars is being observed, up close and personal.  And, like the Hi-RISE camera on Nasa’s Mars Reconnaissance Orbiter, Mars Express has some specialised instruments more…

Time-lapse: Earth

As the Guardian’s GrrlScientist says, “Wow. Just wow.”  And, “Oh, I recommend “full screen” mode.” Indeed. Adds – If you watch closely you can see Ireland and the UK pass underneath at around 2mins 30secs in. Time-Lapse | Earth from Bruce W. Berry Jr on Vimeo.

A year of Curiosity

Curiosity view of Mars

One year ago, after “seven minutes of terror“, Nasa’s Mars Science Laboratory, the 900kg rover Curiosity, landed safely on the Red Planet and was soon taking a look around.   [Image Credit: NASA/JPL-Caltech/Malin Space Science Systems]  Full image and caption here. This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera more…

“There’s no place like home…”

Cassini image of Earth in Saturn's rings

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…

Three Years of SDO Data – Narrated

If you enjoyed the recent video from Nasa’s Solar Dynamics Observatory (SDO) – “Three years in three minutes” – but would have liked more of an explanation of what was going on with our own local star… here it is again!  This time, though, extended, and narrated by NASA’s Goddard Space Flight Center heliophysicist Alex Young. more…

“A major difference between the hurricanes is that the one on Saturn is much bigger…”

Cassini - Saturn north pole The Rose

As I mentioned previously, Saturn doesn’t get the love some of our other gas giants do.  [All hail our friend and lord, Jupiter!  Keeping Ogdy at bay… – Ed]  Indeed… [new link]  But, with the help of Cassini, Saturn does provide some wondrous images.   In some of its first sunlit images of Saturn’s north pole, Cassini has looked inside more…

Solar Dynamics Observatory: Three years in three minutes

What it says on the tin.  Three years after First Light, Nasa’s Solar Dynamics Observatory (SDO) has released three stunning minutes of images compiled during its virtually unbroken coverage of the sun’s rise toward solar maximum.  Enjoy!  [Video from NasaExplorer on YouTube.

Comet 2013 A1: Rendezvous with Mars…

Comet 2013 A1 (Siding Spring) orbit

Here’s something to think about whilst waiting to see if Comet ISON will fizzle, or sizzle.  The latest Science at Nasa video looks at the trajectory, and consequences for Mars missions, of Comet 2013 A1 (Siding Spring).  Discovered as recently as 3 January this year, this Oort cloud object will pass “extraordinarily close” to the planet Mars on more…

The ALMA Inauguration

As the BBC reported on Wednesday, having opened its eyes in 2011, and with 57 of its 66 antennas now ready to receive data on the Chajnantor Plateau in the Atacama desert, Chile, the Atacama Large Millimetre/Sub-millimetre Array (ALMA) was officially inaugurated on March 13.  Here’s the associated ESOcast 55: The ALMA Inauguration.

“President Vladimir Putin said he thanked God no big fragments had fallen in populated areas.”

As I mentioned previously, asteroid 2012 DA14 is due to make its close encounter with Earth later this evening.  Meanwhile, earlier today several hundred people in the Chelyabinsk region of Russia were injured during a visitation by the god Ogdy by debris caused by the unexpected appearance of a relatively large meteor.  It’s reported that a crater 6m (20ft) wide more…

Pope Benedict XVI: “with full freedom I declare that I renounce the ministry of Bishop of Rome”

For anyone seriously concerned with his “legacy”, the surprise announcement by Pope Benedict XVI, of his intention to renounce the ministry of Bishop of Rome “as from 28 February 2013, at 20:00 hours”, deserves a more considered approach.  For example, following on from his initial response, at the Telegraph Blogs Damian Thompson reproduces the Catholic more…

“Ireland has the potential to generate far more wind energy than we could consume domestically…”

Apparently, Ireland is to become Britain’s off-shore wind farm…  That seems to be the gist of the complaint from opponents to wind farms in the Irish Midlands, as reported in the Irish Times. Andrew Duncan, spokesman for the Lakelands Wind Information Group in Co Westmeath, said: “It seems to be an Irish solution to a British more…
