Curiosity view of Mars

A year of Curiosity

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…

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…

Cassini - Saturn north pole The Rose

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

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.

A5 ruling: “They should not be left in any doubt about what may or may not occur…”

The Northern Ireland Department for Regional Development have 7 days to appeal the Belfast High Court ruling issued today quashing the decision to go ahead with the controversial A5 £330m dual carriageway project.  As the BBC reports Following the verdict, lawyers for the department sought to have the court order put on hold.

Comet 2013 A1 (Siding Spring) orbit

Comet 2013 A1: Rendezvous with Mars…

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…

“Two European countries, Ireland and Norway, have already banned all eel fisheries.”

But not in Northern Ireland.  [Partitionist! – Ed]  Indeed.  Here the regulation of eel fisheries is the responsibility of the Department of Culture, Arts and Leisure – and the current Minister, Sinn Féin’s Carál Ní Chuilín.  As is salmon fishing… There was a brief flurry of press statements last week as the NI DCAL Minister suddenly threatened 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…

Comet C/2012 S1 Oct04 2012

“Will Comet ISON fizzle … or sizzle?”

Science at Nasa has a great assessment of the potential for Comet C/2012 S1 (ISON) to become the ‘Comet of the Century’.  Worth watching. Just remember – “comets are like cats: they have tails, and do whatever they want to do.” But as the Science at Nasa assessment notes “Comet ISON is probably at least twice as more…

Comet C/2012 S1 Oct04 2012

“comets are like cats: they have tails, and do whatever they want to do”

In the BBC’s science news preview of 2013, reporter Jason Palmer highlights a couple of astronomical events worth keeping an eye out for. In mid-February we will get another reminder we live in a (potentially) violent cosmos – asteroid 2012 DA14 will make a harmless but attention-grabbing pass near the Earth, at a distance just a tenth more…

“the looming legal row, which is due to commence on 9 January, could become a defining event for Northern Ireland…”

Well, perhaps.  At the very least it might provide the basis for some actual politics, for a while…  ANYhoo…  The Observer’s Jamie Doward with a reminder of the upcoming legal battle over planning permission for the Bushmills Dunnes development – a 18-hole golf course, clubhouse, golf academy, 120-room hotel and 75 golf lodges complex, plus associated car more…

Nasa: Black Marble Earth

Black Marble Earth

As the BBC’s Spaceman, Jonathan Amos, notes This [above] spectacular night-time view of Earth is called Black Marble. It has been assembled from a series of cloud-free images acquired by one of the most capable satellites in the sky today – the Suomi spacecraft. Here is the associated, wondrous, video from Nasa Explorer This view of Earth more…

Fermanagh Crannog 2012: bone comb with incised decoration

“The new A32 Cherrymount link road near Enniskillen will eventually be built on top of the crannog…”

The BBC reports, as do other news outlets, the Northern Ireland Environment Minister’s press release on “the first substantial, scientific excavation of a crannog in Northern Ireland”.  A “huge treasure trove of artefacts” was uncovered – potentially of “international importance” – and the crannog was occupied from at least AD 900 to AD 1600.  The ministerial press release also more…

The BBC report that the National Trust have amended the controversial exhibition at the new Giants’ Causeway interpretive centre following their announced review of the materials in the display.  But have they fully addressed the problem?  Not quite. Here’s how the revised controversial section of the transcript now reads Today there is a clear understanding among scientists that more…

Jupiter swallows an asteroid – redux

As Space Weather notes Around the world, amateur astronomers have been scanning the cloudtops of Jupiter for signs of debris from an explosion witnessed by Dan Peterson and George Hall on Sept. 10th. So far the cloud layer is blank. “Several observers have now obtained excellent images on the second and third rotations after the more…
