Please note that the following list of Cosmic Events of 2018 is incomplete and does not cover the entire year because not all 2018 events have been written about and published yet!
As you know, each year begins under the influence of the Winter Solstice planets of the prior year which in this case is the Winter Solstice of 2017. Its solar influences extend at least until Spring Equinox 2018 in March.
Astrologically, year 2018 itself opens with a Cancer Full Moon at '12 Cancer' which is the "A Chinese Woman Nursing a Baby with a Message" degree suggesting an "occult potential of being, one that requires a deeper or higher 'vision', a holistic perception...; Keynote: The revelation of latent worth in an experience once it is seen in its deeper meaning." REVELATION."
The symbol for the January Full Moon's prior degree of karmic confrontation is '11 Cancer' = "A Clown Caricaturing Well-Known Personalities"; "Keynote: The value of humor in developing objectivity and independence of mind. DECONDITIONING." Mr. Trump pontificating from the White House has been a comedy bonanza for our erstwhile late night funny men and stand-up comics and a safety valve for Americans and others who appreciate their efforts to make us laugh to keep from crying.
Then, after a very long year 2017, the Trump (excuse for an) administration has its Inauguration 2018 Solar Return (horoscope shown with POTUS Sun in 6th house, quirky Uranus at Midheaven--is this Return chart showing a change of occupation or residence? Poor health due to too much fast-food eatin'? Use of military and police forces? Any, all, or none of these?) All bets are off on whether insulter-in-chief Trump remains in the White House into 2018 and/or beyond. After all, last evening's election results in Virginia, New Jersey, and elsewhere favored Democrats over Republicans as a rebuke to Peckerwood Trump and his party of billionaires and racists!
Now three Solar Eclipses occur in 2018 and are repeats of year 2000 (there was a fourth solar eclipse on Christmas Day 2000 @4Capricorn, the repeat of which manifests in the 2 South series on January 6, 2019 @15Capricorn.) Obviously these solar eclipses of 2000 occurred before the 'New Millennium' dawned and prior to the attacks of 9/11. Currently we are under the auspices of a 1 North Solar Eclipse which manifested as The Great American Eclipse of August 21, 2017 @29Leo--conjunct Mr. Trump's natal Ascendant (his nibs himself).
Next up is the 1 South Solar Eclipse or what I'm calling The 'We The People Eclipse' of February 15, 2018 @27AQ (conjunct US natal Moon of July 4, 1776). We receive a 'cosmic blink' from this 'wild card of the Universe' as more secrets are starkly revealed by eclipse light.
And on May 15, 2018 rebellious, disruptive Uranus Enters Taurus, a money sign ruled by comfort-loving Venus and signaling a period of risking everything in one toss, speculation, and/or seeking individual methods of financing (Ebertin).
Then on July 13, 2018 it's a Solar Eclipse @21Cancer in the 2 Old North series which is the Prenatal Eclipse (PE) series of quixotic Donald J. Trump, swamp-drainer extraordinaire (not!) His 2 Old North PE occurred on June May 30, 1946 @8Gemini conjunct US natal Uranus which suggest potentials for revolution, resistance, protests, unrest of the people due to his actions and rhetoric, upsets in the nation, a break for freedom, and/or violence.
Note that one of the historical events of early 1946 include President Truman setting up the CIG (Central Intelligence Group) but he signed the National Security Act on July 26, 1947 and you may wish to view the CIA's Neptune Rising natal horoscope here. The secretive organization is a Saturn-Pluto/Mars-Uranus/Moon-Jupiter affair and will experience a three-fer Jupiter Return (17Sco52) on January 6, May 12, and September 5--all in 2018. See The History of the CIA for copious historic details.
The third and final Solar Eclipse of 2018 is The 'Tower Eclipse' of August 11th in the 2 New North series with its 'collapse of an existing structure' theme that resonates closely with Tarot card 16. This eclipse also resonates by degree (19Leo) with the 18 North Solar Eclipse of August 11, 1961, the PE of FOX News personality Sean Hannity (in case you're a fan). Current-day, 18 North manifested on September 13, 2015 @20Virgo with themes of 'high stress level, taxing of strength, physical concern' (Brady).
And on November 5, 2018--around the time of the 2018 Midterm Elections--it so happens that US Constitution's Progressed New Moon perfects at 16Tau03 (chart shown). '17 Taurus' = "A POLARIZATION OF VALUES" (symbol: "Swords vs Torches"). This Sabian Symbol is so full of esoteric meaning concerning the founding of America that a book would have to be written!
Then beginning in December 2017, Ronald Reagan and his policies and political legacy of 'trickle down' economics has a three-fer Jupiter Return to his natal Jupiter position (13Scorpio) which extends into 2018 as transit Jupiter, banking planet of jackpots and lotteries, expands himself along through the secretive and ruthless business sign of Scorpio.
Well, there is my partial list of previously published posts concerning 2018. Knowing myself as well as I do, updates to this list as posts are published probably won't be happening but a reader can always plug '2018' into the sidebar Search Box and see what appears!
Blog note: if you haven't yet please answer the sidebar Trump Poll which will only take a moment. So far the top answer is, Not in this lifetime!
